Round up a float number

Hi!
Which Math function do I have to use to round up a float number ? I thought the correct one was the Math.ceil() function but I don't get what I need. I mean, which is the correct function to get the following result:
Math.function(2.75)=3
Thanks

This is what I get:
Math.ceil(2.75)=2I get 3.0 for that calculation. You must be doing something besides the raw calculation. Here's my code that tests it:public static void main(String[] args) {
System.out.println(Math.ceil(2.75));
}Let's see yours.

Float number rounding

how can I determine whether the number of digits after decimal point is greater than one? For e.g., the float number of 16.04(or more digits) should be rounded, but the number of 16.1 should not be rounded.
Is there any other convenience method except the split method in String class?
thanks in advance.

Yes, the formula you mentioned is what I'm using to round the float number to the tenth place.
float f = ...;
f = Math.floor(f*10) / 10;
but the float number I'm choosing to be rounded should have the number of digit numbers after decimal point greater than one, for e.g.,
f = 16.045 need to be rounded to 16.0 using that formula
f = 16.01 ......
f = 16.0 need not to be rounded since it aready just have one digit number after decimal point
f = 15.9 ......
sorry about the confusion. thanks for your help.

How is it possible to precise a float number in java

Hello ,
It is my second post and i couldnt find an answer to it. The problem ii want to display a float number with only the last three decimal after the comma. For example, float x = 23.445566 and i need to display only 23.445
How can i do that ? here is the code:
int val1 = 1432;
int val2 = 13;
float result = 0.000F
(float) (valu1/valu2)
the result = 110.153846...
And what i want to display is 110.153
Please help.
Thanks

You're right - java.text.Decimal format uses round half even, java.util.Formatter uses round half up.
    Float f = 0.5F;
    System.out.printf("%.0f\n", f);
    System.out.println(new java.text.DecimalFormat("0").format(f));

0In the ASNI C implementations I've worked with, printf also uses half-even.
Bizarre.

Appears to be right, but don't forget to round to the nearest integer.

Rounding off 2 decimal number

Hi,
How can i round up float number to two decimal number.
For example
Number is 45.987654532 then It should be rounded up to 45.98
Number is 45.987654546 then It should be rounded up to 45.99Appriciated sample souuce (If any)
Tanks in advance

You could have a look at String's format() method. The format strings are
described in detail here:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.htmlpublic class Round {
    public static void main(String[] args) {
        double number = 45.987654546;
        String roundStr = String.format("%.2f", number);
            // Rounded is 45.99
        System.out.println("Rounded is " + roundStr);
            // The same thing
        System.out.printf("Rounded is %.2f%n", number);
}Note: these methods generate rounded Strings from floating
point numbers. Also, they round to a string representing the "nearest"
number - your first example is a little hard to understand in this regard.

Error in mapping for floating Number calculation

Hi All,
   I have a small doubt in floating number calculation in Mapping.
Actually i am geting a floating point number and calculating the SUM and generating the output. The input is of 2 decimal places(Ex: 26.02 and 26.03 ), but when it is adding all the values it is generating a three digit decimal number (Ex: 52.050003)
I dont know from where it is geting one extra number "2" in the output.
Please find the code for the same and let me know if i need to do something else to get ride of this.
   //write your code here
float sum=0;
if(a != null && a.length > 0.00)
   for ( int j =0; j<a.length;j++)
    sum = sum + Float.parseFloat(a[j]);
   result.addValue(String.valueOf(sum));
else
result.addValue("0");
Thanks in Advance,
JAY

Jay,
Please use the below code and let us know, if it helps.
BigDecimal sum= new BigDecimal("0");
BigDecimal bd;
if(a != null && a.length > 0.00)
for ( int j =0; j<a.length;j++)
bd=new BigDecimal(a[j]);
sum=sum.add(bd);
result.addValue(""+sum+"");
else
result.addValue("0");

Purchase Order value rounded to a single number

How is the Purchase Order value rounded to a single number ?
Ex: Example - 100.51 to be rounded to 101 OR
100.49 to be rounded to 100
It is required at PO - Price conditions . (Item details----material net price )
(and also in PO output screen which can be done with the help of developer)
regards,

Hi,
Go to
SPRO - > MM -> Purchasing -> Define price detmination process -> define condition types -> go for define condition type -> select any condition type -> go to details -> inside it you will see the Rounding rule -> choose 'A'
Save your enteries...and check..
Hope it helps..

How to get the amplitude of a sound as a float number in Java

Hi, I would like to create a program which plays an audio file(it may be a midi, probably) and it returns
the amplitude of the sound in terms of float number.
I mean, is it possible to obtain this number, since every sound file is actually a sequence of float number like
110.010110101 etc.
Can you help me with suggestions and details about the way to take.
Regards
Frank

For sampled sound, the answer might be seen in [ this thread|http://forums.sun.com/thread.jspa?messageID=10636576#10636576]. For MIDI it is different in that you will only be able to get it as sampled sound once it has been synthesized, and as I recently found out, to get the audio coming through the regular sound lines will take nothing less than a physcical or software 'audio loopback' being installed, on most PCs.
Of course, if it is MIDI, you might just cheat by calculating a 'volume' from the note velocities in the MIDI score.

Rounding to a whole number

What is the proper syntax for rounding to a whole number. In my spread sheet I have a function set up to apply a divisor to cost, in this case = F7 $625 / G7 .65 = $961.54. I simply want the number to round to the nearest whole dollar amount $962.00

Hi ghemmen,

Converting string to float number

Here's what I'm trying to do. The user types a number, such as 12.011, in an input box. I want to check to see if the number they typed is between two numbers, such as 12 and 12.1. Therefore, I want to convert the string in the input box to a float number, not an integer, so I can check to see if it's in the correct range. How do I convert a string into a float number?
thanks
Mark

Did you try:
Number(textinput1.text);
if(Number(textinput1.text)>12 && Number(textinput1.text)<12.1)

Rounding off a float to two decimal places

I want to make a function where I shall pass a float and and integer.
The float shall have to be rounded off to a value in the integer.
Can anyone please suggest how to round off a float.
E.g.: if the float is 12.56890 and I want to round it off to 2 decimal places, then it should be 12.57.
Regards
Hawker

I didn't mention any datatypes like float, double.True, but that is what the question is about, so you weren't answering the question. For a change.
As I mentioned, that was just a mathematical steps to round of the floating point value. (Not in any programming languages point of view).False. You didn't mention that at all.
This is the code for that in java.So here you are mentioning datatypes and floats for the same piece of mathematics that you have already been told, with reasons, doesn't work in floating point.
which seems to be working fine
Seems to. What evidence do you have that the float actually got rounded? As opposed to got displayed as rounded? Which is not what the OP asked for.
And of course all that code seems to do is round 0.01 to two decimal places, which again is not what the OP asked for.
For any remaining fans of this 'technique', please explain the behaviour of the following code:
     public static void     main(String[] args)
          int     count = 0, errors = 0;
          for (double x = 0.0; x < 1; x += 0.0001)
               count++;
               double     d = x;
               int     scale = 2;
               double     factor = Math.pow(10, scale);
               d = Math.round(d*factor)/factor;
               if ((d % 0.01) != 0.0) // if 'd' really has been rounded this should be zero
                    System.out.println(d % 0.01);
                    errors++;
          System.out.println(count+" trials "+errors+" errors");
     }

How to convert timing to floating number

hi everyone, i want to do a time measurement of hall sensor and use this value to set a frequency and also to use as process value in a PID controller. the problem is that i get an dynamic data output and i'd like to have this in a floating number, is this possible? or another way is also good... hereby a jpeg to make it more clear.
i also get more problems with this, when i change the throttle (0-100%) is doesn't do anything and my while loop also doesn't end anymore. this is just a small part of the complete program, maybe it's to heavy for my comp? (single core 1,6Ghz, 1,5gig ram)
hope it's a little bit clear what i mean
thanks in advance !
P.S: i know that the divide by one is useless because you can directly measure the frequency, this has allready changed.

hi thanks for the reply, the answer you gave helped me out.
now i've noticed that when i ad the the pid loop (even when nothing of it is connected) the program doesn't respond anymore. is this because of my computer? the while loops (both the normal and pid loop) are stopped by a single switch...
i have uploaded my VI so maybe someone could check it out, be aware it's totally not finished ^^. if you delete the pid control you'll see what i mean.
thanks in advance

Round up float number

Hi,
I have to manage floats with euro format .
here's the code :
<CODE>
float first = 78.31;
float second = 1.81;
float tot = first + second;
</CODE>
the result of thi addition is tot = 80.11999......
sigh!!
how can i round up this number with 2 digits of precision ?
(tot = 80.12)
thx

You don't. But you can format it rounded. (i.e., the stuff in the java.text package, like DecimalFormat).
Or you can represent the value using ints. (E.g., create a Euro class and have two ints, one for the whole euro value and one for the fractional euro value.
Or you can use java.math.BigDecimal.
This issue keeps coming up. Check the forum for a recent thread about fractions.
