Preserved Topic: a little hint on JAVA plz

Hey:

if I have
float n = 12.34;
how can I get the length of the variable? For instance, in this case it's obviously 5 characters including the decimal point. But if n is unknown, how can I know how many characters there is in it?
(I tried n.toString(), but compiler said it can't be dereferenced)

thanx alot.

are you sure you can cast a float on string? (inconvertible types)
im no java-expert, but i doubt this is possible.
*waits to be corrected *

It's been a while since I did any reading in my Java book, but I think you should a least be able to (as InI suggests) cast the float to a string, and then check it's size.

And like Grumble...

I also wait to be corrected

You can use the static method "toString" of the "Float" class.

Float.toString(n).length();

Notice you are not type casting such as

String x = (String)float;

you are type casting by adding the float to a string.

String x = "" + float + "";

This is the same as any other form of creating a string with variables added. Just notice you are casting it by adding two null values to either side.

thank you very much Ini, and everybody else that intended to help.

I like s = "" + n + "";

man, I used that trick quite alot when I was playing with javascript.
and damn me, all those upcasting and downcasting and exceptions really reeally got my brain out.

sincerely, I appreciately all you help !!
