String to number - Resolved

[Phenglai]

Guys,

I am having a problem converting a string over to a value like Float or double. I am teaching myself J++ right now and I am trying to convert a VB program I wrote into J++.

I need to convert the string value that is in the edit box into a float value. I have tried to use the valueOf but it keeps telling me that there is not valueOf part of the class.

I have tried all the examples that are listed here and cant seem to get any of them to work. MS does not seem to have the parseItem in there stuff.

Can anyone help me out. I have not seen very much on here for J++ but its all I have to learn from right now.

Thanks,

Jerel

I have never used J++, but in plain Java, you could use...

float f = Float.parseFloat("2.1");

Does that help?

No, the types dont have the parseFlost or parseDouble function in them.

Its wierd, I cant seem to figure it out at all. If you go to msdn, they dont have help on J++ anymore there, heck they dont even have VB 6.0 hardly anymore.

I have 4 books on J++ and none of them talk about this. They all go the other way from value to string but not string to value.

Well, I figured it out. Here it is if anyone ever needs to figure this out on J++

float f = Float.valueOf(String).floatValue();

Same as in Java.
BTW, J++ is a bad language to learn. It is discontinued by MS and support will go rapidly away as Sun has won the lawsuit about it against MS.

Learn real Java or learn C#.

That is my plan but all I have is J++ right now. The forms on J++ are the precursor to the windows forms of .Net and the syntax, while not the same, is close and can give me a headstart until our company buys .net or Java. Depending on which way we turn.

Thanks,

Java is free...
