Dtrace Floating Point gives error on x86

When I try to create a floating point constant in dtrace x86:
BEGIN
printf ("%f", 1.0);
exit (1);
I get the error:
dtrace: failed to compile script special.d: line 3: floating-point constants are not permitted
Am I using the floating point constant incorrectly, or are floating point constants not permitted in the x86 platform.
Thanks,
Chip

Then what is meant at the bottom of page 48 of the
Solaris Dynamic Tracing Guide where it talks about
floating-point constants?
ChipSorry for not making that sufficiently clear. We are reserving that syntax for possible future use, but you cannot specify floating-point constants at present, and you cannot perform floating-point arithmetic in D. The only legal use of floating-point is that you can trace one or more data objects or structures that contain floating-point values and format the results using printf() and the various %f, %g formats.

  • Floating Point Arithmatic Error

    Hi,
    I know actionscript represents numbers and double precision
    floating point values. I'm having a problem where double arithmatic
    in actionscript doesn't match the results of the same double
    arithmatic in C++ / C#.
    EXAMPLE:
    In C++ / C#:
    double x, y, x1, y1;
    x = 209.4;
    y = 148.8;
    x1 = 203.0;
    y1 = 145.0;
    double ddx = x - x1;
    double ddy = y - y1;
    RESULT
    ddx: 6.4000000000000057
    ddy: 3.8000000000000114
    In Flash ActionScipt 2:
    var x, y, x1, y1;
    x = 209.4;
    y = 148.8;
    x1 = 203.0;
    y1 = 145.0;
    var ddx = x - x1;
    var ddy = y - y1;
    RESULT
    ddx: 6.39999999999992
    ddy: 3.80000000000024
    After researching Flash / Actionscript "var" stores numerical
    values as doubles ( 8 bytes ) just like doubles are stored in C++ /
    C# ( 8 bytes ). Why would there be a difference between the results
    of ddx and ddy? Are there different implementations of double
    floating point math? If so, Is there a way I can mimic the Flash /
    Actionscript version in C++ / C#?
    Any help would be great!
    Thanks!

    Hmmm, so you're saying the actual binary representation is
    the same but they're just displayed differently?

  • Floating point rounding error

    I've been working on an egyptian fraction program and for some reason I cant seem to figure out a way to fix this rounding error. An egyptian fraction is a fraction that can be expressed as a sum of fractions eg. 3/4 = 1/2 + 1/4. For some reason on certain fractions it rounds up and skips the correct fraction to subtract. When I run 2/7 its supposed to equal 1/4 + 1/28, but gives me 1/4 + 1/29 and decides to round. This is my code for the problem.
    public class EgyptianFraction{
        private static double epsilon = 1.0e-7;
        public static void main(String args[]){
            greedySearch(2.0/7.0);
        public static void greedySearch(double fraction){
            for(int i = 2; fraction > epsilon; i++){
                if(fraction - (1.0/i) >= 0){
                    fraction -= (1.0/i);
    //*****Output******
    //0.0357142857142857 - 0.03571428571428571 = -1.3877787807814457E-17
    }When I print out all of the math involved it says that it gives the output above. They are fairly close but for some reason it makes the 1/28 bigger then the current fraction. The program should subtract 1/28 and then the fraction should be close enough to 0 and end. Is there any way you guys can think of to fix this problem?

    You have given the error as epsilon, so you can't expect `fraction - 1.0/i >= 0` to give an exact answer.
    Given your error is +/- epsilon, this expression should be
    fraction - 1.0/i >= epsilon || fraction - 1.0/i >= -epsilon
    or just
    fraction - 1.0/i >= -epsilon
    If you change this you get 1/4 + 1/28 as the answer,

  • EF Code First: FLOAT Columns generate [Column(TypeName = "float")], which give errors

    When I create a simple table with a FLOAT(126) column and add an ADO.NET Entity Data Model with Code first from the database I get a decimal for the FLOAT column with the following ColumnAttribute: [Column(TypeName = "float")].
    When I try to add a controller for this generated Code First class, it fails with the following message:
    Error:
    There was an error running the selected code generator:
    'Unable to retrieve metadata for 'MyNamespace.TEMP_WITHFLOAT'.
    Schema specified is not valid. Errors:
    (8,12) : error 2019: Member Mapping specified is not valid. The type 'Edm.Decimal[Nullable=False,DefaultValie=,Precision=38,Scale=0]' of member 'FLOATCOL' in type 'MyNamespace.TEMP_WITHFLOAT' is not compatible with 'SqlServer.float[Nullable=False,DefaultValue=]' of member 'FLOATCOL' in type 'MySchema.TEMP_WITHFLOAT'.'
    It fails with the same error if I specify other values for precision and scale (or remove the lines entirely) in the code invoking HasPrecision in the generated model.
    The error message when trying to add a controller for the generated class:
    But - if I remove the attribute [Column(TypeName = "float")] from the generated Code First class, the controller is created without errors, and works as it should, returning decimal numbers correctly (it happily ignores that the scale is set to 0 in the generated model).
    The generated class with the ColumnAttribute removed:
        [Table("MYDBSCHEMA.TEMP_WITHFLOAT")]
        public partial class TEMP_WITHFLOAT
            [DatabaseGenerated(DatabaseGeneratedOption.None)]
            public int ID { get; set; }
            //[Column(TypeName = "float")]
            public decimal FLOATCOL { get; set; }
    Correct JSON output from working controller:
    [ { "ID": 1, "FLOATCOL": 123.0 }, { "ID": 2, "FLOATCOL": 123.456789012345 } ]
    It would be very nice if the Code First generated classes worked out of the box, without a required step to manually remove the Column attribute for every FLOAT column.
    Is there a workaround or other solution to this problem? The best solution would be if the generated code is mapped correctly between compatible database and C# types.
    Simple code to reproduce the issue:
    SQL script for the table:
    CREATE TABLE "TEMP_WITHFLOAT"
       ( "ID" NUMBER(10,0) NOT NULL ENABLE,
      "FLOATCOL" FLOAT(126) NOT NULL ENABLE
       ) PCTFREE 10 INITRANS 1 NOCOMPRESS LOGGING;
    ALTER TABLE "TEMP_WITHFLOAT" ADD CONSTRAINT "PK_TEMP_WITHFLOAT" PRIMARY KEY ("ID") ENABLE;
    The generated class:
       [Table("MYDBSCHEMA.TEMP_WITHFLOAT")]
        public partial class TEMP_WITHFLOAT
            [DatabaseGenerated(DatabaseGeneratedOption.None)]
            public int ID { get; set; }
            [Column(TypeName = "float")]
            public decimal FLOATCOL { get; set; }
    The generated model:
        public partial class TempWithFloatModel : DbContext
            public TempWithFloatModel()
                : base("name=TempWithFloatModel")
            public virtual DbSet<TEMP_WITHFLOAT> TEMP_WITHFLOAT { get; set; }
            protected override void OnModelCreating(DbModelBuilder modelBuilder)
                modelBuilder.Entity<TEMP_WITHFLOAT>()
                    .Property(e => e.FLOATCOL)
                    .HasPrecision(38, 0);

    The annotation is emitted by the entity designer because it is necessary to preserve type fidelity with the source database column.
    If the annotation is removed, the FLOATCOL property in the generated class would map to an Oracle number(38) column. But, of course, that is not what the source column is in this case.
    For example, this would be a problem if a database initializer was subsequently used to re-create the database or if a script was generated via migrations using the class without the annotation.
    It's interesting that the error message refers to SqlServer.float type.
    I'll try to investigate a bit more...

  • Floating Point Representations on SPARC (64-bit architecture)

    Hi Reader,
    I got hold of "Numerical Computation Guide -2005" by Sun while looking for Floating Point representations on 64 bit Architectures. It gives me nice illustrations of Single and Double formats and the solution for endianness with
    two 32-bit words. But it doesn't tell me how it is for 64-bit SPARC or 64-bit x86.
    I might be wrong here, but having all integers and pointers of 64-bit length, do we still need to break the floating point numbers and store them in lower / higher order addresses ??
    or is it as simple as having a Double Format consistent in the bit-pattern across all the architectures (Intel, SPARC, IBMpowerPC, AMD) with 1 + 11 + 52 bit pattern.
    I have tried hard to get hold of a documentation that explains a 64-bit architecture representation of a Floating Point Number. Any suggestion should be very helpful.
    Thanks for reading. Hope you have something useful to write back.
    Regards,
    Regmee

    The representation of floating-point numbers is specified by IEEE standard 754. This standard contains the specifications for single-precision (32-bit), and double-precision (64-bit) floating-point numbers (There is also a quad-precision (128-bit) format as well). OpenSPARC T1 supports both single and double precision numbers, and can support quad-precision numbers through emulation (not in hardware). The fact that this is a 64-bit machine does not affect how the numbers are stored in memory.
    The only thing that affects how the numbers are stored in memory is endianness. SPARC architecture is big-endian, while x86 is little-endian. But a double-precision floating-point numer in a SPARC register looks the same as a double-precision floating-point number in an x86 register.

  • Byte Order for Floating Point Types

    I need to send an array of floating point values from an x86 C++ application to a Java application. I am using a socket to transfer the data. What, if anything, do I have to do about preserving the correct byte order?

    Probably nothing.
    If you do end up having a problem, look at the java.nio package. Specfically, java.nio.ByteOrder, and java.nio.Double/FloatBuffer.
    To be completely safe, I think I'd probably send an enum in some kind of header that indicates what byte order your C++ is sending and use the *Buffer classes to automatically handle the conversion.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

  • [solved] my C code gives floating point errors.

    I've tried to create a simple function to determine if a number is prime or not.. whenever I compile and try to run I get a floating point exception and can't quite figure out why, I'm very new to C and compiling manually using gcc so any help is appreciated.
    here's my code: http://pastebin.com/m2f19dbac
    Last edited by zandaa (2008-10-01 06:36:35)

    I'm quite useless at programming:
    for (i=0; i <= x; i++) {
    if (x%i == 0 && i != 1) {
    result = 0;
    //break;
    if (i == x) {
    result = 1;
    //printf("%d\n", x);
    break;
    This loop always ends with result=1 because the last loop has i=x and therefore it changes the result value to 1.
    There are also many checks you could avoid with a "smart" for cycle:
    for (i=2; i <= x; i++) {
    if (x%i == 0) {
    return 0;
    return 1
    I was able to remove the "i != 1" part by having the for loop starting from 2.
    I removed all the if (i == x) clause because that only happens at the end of the for cycle.
    Also you could be smart and eliminate some values from the loop: for example you could avoid checking all the numbers higher than n/2 or than sqrt(n), but that's more related to the mathematics behind than to the programming
    Hope this helps

    Good Evening,
    I have been having this problem with Adobe Bridge for a while and tonight sat down to try and solve it. Fresh version of Windows XP reinstalled all programs and this is still happening! Any Ideas?
    This error only occurs with Adobe Bridge, I can load Photoshop etc.. all fine.

    Is there are answer to this problem?  This error message is appearing on an entire lab full of computers.  We are running Web Premium CS4
    I have tried to reset the Bridge Preferences:
    Hold down the Ctrl key and click on Bridge icon to start.
    Should get a reset window with 3 options.
    Choose the first option
    I still get "Runtime Error!   Program: C:\Prgram Files\Adobe\Adobe Bridge CS4\Bridge.exe  R6002 -floating point support not loaded"

  • Invalid Floating Point Error

    iMediaTouch probably doesn't support Floating Point formats - it certainly doesn't mention them in the advertising. Try saving your files as 24-bit PCMs, and they should import fine.

  • Designing for floating point error

    Hello,
    I am stuck with floating point errors and I'm not sure what to do. Specifically, to determine if a point is inside of a triangle, or if it is on the exact edge of the triangle. I use three cross products with the edge as one vector and the other vector is from the edge start to the query point.
    The theory says that if the cross product is 0 then the point is directly on the line. If the cross product is <0, then the point is inside the triangle. If >0, then the point is outside the triangle.
    To account for the floating point error I was running into, I changed it from =0 to abs(cross_product)<1e-6.
    The trouble is, I run into cases where the algorithm is wrong and fails because there is a point which is classified as being on the edge of the triangle which isn't.
    I'm not really sure how to handle this.
    Thanks,
    Eric

    So, I changed epsilon from 1e-6 to 1e-10 and it seems to work better (I am using doubles btw). However, that doesn't really solve the problem, it just buries it deeper. I'm interested in how actual commercial applications (such as video games or robots) deal with this issue. Obviously you don't see them giving you an error every time a floating point error messes something up. I think the issue here is that I am using data gathered from physical sensors, meaning the inputs can be arbitrarily close to each other. I am worried though that if I round the inputs, that I will get different data points with the exact same x and y value, and I'm not sure how the geometry algorithms will handle that. Also, I am creating a global navigation mesh of triangles with this data. Floating point errors that are not accounted for correctly lead to triangles inside one another (as opposed to adjacent to each other), which damages the integrity of the entire mesh, as its hard to get your program to fix its own mistake.
    FYI:
    I am running java 1.6.0_20 in Eclipse Helios with Ubuntu 10.04x64

  • Error on floating point?

    One can expect that 1.2 * 3.0 equals 3.60
    But the following statement has the result: 3.5999999999999996
    - System.out.println(1.2 * 3.0);
    Why?
    How can I control or estimate the floating point error?
    Thanks in advance!

    It is not a Java problem or a Java error. It is inherent to floating-point arithmetic.
    1.2 can not be exactly represented in binary floating-point arithmetic. But 1.25 (that is 5 * (2 ^ -2)) can be.
    If your problem requires exact decimal arithmetic, use BigDecimal instead. (It is very slow compared to the conventional floating-point arithmetic).
    Please consult a textbook on numerical calculus for the techniques of dealing with floating-point error - it depends on the algorithm that you use for solving your problem.

    Can anybody help me quick?

    If the platform is CLDC 1.1 you can have floats. Run preverify to see the options. The cldc1.1 preverifier seems to have options to allow rejecting floats/doubles but the default seems to be to allow them.
    Usage: preverify [options] classnames|dirnames ...
    where options include:
    -classpath <directories separated by ';'>
    Directories in which to look for classes
    -d <directory> Directory in which output is written (default is ./output/)
    -cldc1.0 Checks for existence of language features prohibited
    by CLDC 1.0 (native methods, floating point and finalizers)
    -nofinalize No finalizers allowed
    -nonative No native methods allowed
    -nofp No floating point operations allowed
    @<filename> Read command line arguments from a text file
    Command line arguments must all be on a single line
    Directory names must be enclosed in double quotes (")
