How do I convert a string to a value in a formula

I'm working on a home budget and I've imported my bank records. The records are apparently in a "string" format.
I ultimately want to convert column D to positive integers and use those elsewhere. Simply creating a column that times the values by -1 should work. However I can't use this column in a formula because it contains a string.
Copying a pasting the values still doesn't rid the string error message. In fact, in the new mavericks version, the option to "paste formula results" isn't an option: it's grey.
Any help?

try (just for fun) changing the "," to a "." (period)
I think you localization (on your computer) doesn't match the localization of the values in column D
Numbers automatically justifies an entry based on whe it thinks about the entry.
In the example, above, I entered the text:
"-123,45" in cell B14. Numbers believes it is text and left justifies it.
"-123.45" in cell B15. Numbers believes it is a number and right justifies it.
Since all your entries are left justified Numbers thinks they are text and are, therefore, NOT valid numbers.

You can iterate over the string and use the String to Hex VI. If you work with two bytes of the string at a time you can get a U8 array of the desired binary values. Then when you are complete you can either work with the byte array of convert it back to a string using Byte Array to String.

How do I convert a string, and use a string as a property?

I have an array in the following format:
{ownsCar: 'true', ownsBike: 'true', ownsHouse: 'true'}
{ownsCar: 'false', ownsBike: 'true', ownsHouse: 'true'}
{ownsCar: 'true', ownsBike: 'false', ownsHouse: 'true'}
etc ............
And I need to test against each item e.g.
if...
myDataGrid[myItem].ownsCar == Object(myCheckbox).label
... then
if...
myDataGrid[myItem].ownsBike == Object(myCheckbox).label
... then
if...
myDataGrid[myItem].ownsHouse == Object(myCheckbox).label
... then
But I need to build my application where the property (e.g. "ownsCar", "ownsBike", "ownsHouse") is a variable such as:
if...
myDataGrid[myItem].myProperty == Object(myCheckbox).label
... then
I would like to loop through my Array, counting the number of items, and then use each item as a property.
How would I convert the string (e.g. "ownsCar") into a property "myProperty" ???
Many thanks in advance
Chris

Thanks, but my problem is that I won't know what my property will be.
E.g. they could be...
{svnsdkvnsdklvnsdklv: 'true', seuAfnwfnw: 'true', asfwseionf: 'true', etc.................}
and there could be lots of them.
I need to have myObject[N], where N is a variable property for each of the items taken from a variable length array
so...
ownsCar is represented by myObject.[N]
ownsHouse is represented by myObject.[N+1]
ownsBike is represented by myObject.[N+2]
etc
(sorry, this is so difficult to explain when I dont know what the answer is)

How can I convert a string to a seperated characters?

How can I convert a string to a separated characters without using array?
such as: input = String "word"
output =
w
o
r
d
Thanks

A string is stored internally in individual characters.
The String class has a method 'charAt(int index)' which returns the character at that index so using a for loop..
String s = "word";
for(int counter=0; counter < s.length(); counter++)
System.out.println(s.charAt(counter));

int result = 0;
try
result = Integer.parseString(aString);
catch (Exception ex)
System.out.println ("Failed to convert string " + aString + " to int.");

How do I convert a string into a decimal

I've been tryin to convert a string into decimal but I can't get it to work at all. I keep getting an exception.
I've tried all of these:
double myDouble = Double.valueOf(string).doubleValue();
int myint = Interger.parseInt(string);
float myfloat = Float.parseFloat(string);
I can't get anything to work.
That string i'm reading in is an array containing values with decimals. ex: -45.09348
All the above work fine if there is no decimal, but fails when it comes to one.
How do I go about doing this?
Thanks!

This works for me:String s = "-45.6789";
double d = Double.parseDouble(s);
System.out.println(d);Mark

How do I convert a String to a DateTime in SQL ??

I have retreived the current date and time and place into String data type. but my table colmun is in datetime data type.
How do I convert ??
Thanks in advance.

I have retreived the current date and time and place
into String data type. but my table colmun is in
datetime data type.
take a look at the SimpleDateFormat class...
http://java.sun.com/j2se/1.3/docs/api/java/text/SimpleDateFormat.html
basically something like this...
SimpleDateFormat sdf = new SimpleDateFormat();
java.util.Date dt = sdf.parse(dateAsString);
java.sql.Timestamp ts= new java.sql.Timestamp(dt.getTime());anyway it can handle different formats and i believe you can create your own if you need to.
ps this question would have been better posted in the JDBC forum.

How Do I Convert a String that Names an Object to a Reference to the Object

You get many program-specific object names in the XML that is returned by describeType. Suppose I find an object that interests me. What is the best way to convert the String that names the object (e.g. the id of the object) to a reference variable that points to the object?

Sure. I am working on a complex application that involves several ViewStacks, several Accordions, some checkboxes, some radio buttons, some text boxes. These components are scattered about, but all are children of a base class that is successfully enumerated by
var classInfo:XML = describeType(vwstk);
Suppose I write a loop as follows:
for each (var a:XML in classInfo..accessor){
Inside that loop I have a series of tests like
if (a.@type == "mx.controls::CheckBox"{
Then, I iterate thru all of the children of the base class as in:
for
(var u:Object in vwstk)
{ if
Inside the if I persist the checked/not checked status of the checkbox.
The tricky part is going from the string a.@name to the Object reference u. I doubt my proposed method will work. Do you have a better idea?

How do you convert this String into a double?

Hi, in this code I want to convert String arg into a double. I'm trying to do this so that I can convert some string into a double in this calculator that I'm making. Here is the code:
public class par {
public static void main(String[] args) {
String str = "351";
double arg = new double(str); // should convert the string into a double
System.out.println(arg);
System.out.println(str);
I keep getting errors in line 4, if any of you could help me out here I'll be thankful, i'm kinda new to java and my search for java's equivalent of alof() (its a function in C libraries that converts char[] into a double)lead me to this.

Use the Following:
String num = "123.2";
double d = Double.parseDouble(num);

How do I convert a string to a double, a number loses the precision

I tried converting a string to a double but that limits the precision. I need to convert a string to a double.

If you use the Scan From String function, the default is to convert to a dbl. If you're looking at a front panel indicator, don't confuse the format and precision of the indicator with the type representation. You can set the indicator to display as many digits as you want but that doesn't change the actal number stored in memory.

How to set List of String as variable value in BPEL

I am using java embedding to invoke a method which returns a list of strings. I need to set these values in a variable in BPEL to be used later. I am getting following error while setting the value.
<May 2, 2012 5:18:20 PM IST> <Error> <oracle.soa.bpel.engine.dispatch> <BEA-000000> <failed to handle message

Following is the java code
List<String> providers = Registory.getProviders("1");
setVariableData("providerList", providers);
I have defined a xml element in the wsdl defintion:
<xsd:element name="providerList">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="providerId" type="xs:string" maxOccurs="unbounded" minOccurs="0" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
providerList variable is of type "providerList".
What else do I need to do to convert the List to the xml elements ?

Well I believe this is not officially mentioned anywhere, but this is the limitations for the java embedding activity. You can assign value to a single variable or to the single part element of variable only. I suggest you go with a java web service. you can check more details on java embedding activity @ http://docs.oracle.com/cd/E21764_01/integration.1111/e10224/bp_java.htm

How can I convert a string to an object or class

I would like to read a file representing a class, and convert it to an object or a class (object preferred). Other postings suggest using javax.tools.JavaCompiler to convert from a string but then say that this is not always available (posting on 1 Jan 09). If this is still not universally available is there another way to do this? If this is not available, are there any examples of how it should be done?
My understanding from what I've read is to read the file into a String then compile the String using javax.tools.JavaCompiler, which is an Interface.
thanks

The next guess would to be to create a .jar file and reference it at runtime. Here's the scenario:Eh? How is that even remotely equivalent?
1. People using the 'system' will have a varied knowledge of Java.
2. My hope was to require that anyone using the program would only need to create a Java Class file,You mean a Java source file. You have said that YOU want to create the .class file. If they are creating the .class file, then all you need to do is load it with a ClassLoader and start using it.
You might try clarifying your requirements a bit.
In either case, the Class Files would look like:
public class Name {
int field1;
float field2;
} With all the field types being simple Java Primitives.What is the point of this? What are you ultimately trying to accomplish, that can be served by user-defined groups of primitives, with no complex object graphs and no user-defined methods?
Depending on what you're really getting at, using scripting features via beanshell, groovy, or javascript might be an approach to consider, or using Scala to produce a domain-specific language (although I suspect that last may be overkill, and beyond your current skill level).
If this is so, is there any way to create a .jar file at runtime? Do I have to exec("jar") or is there another way.A .jar file is just a .zip file with a manifest. Look at the java.util.jar package. But note that creating a .jar file has nothing to do with the rest of what you're asking about.
