Jason,
How can you have leading zeros in an int or Integer?
If it's a literal with a leading zero it will be taken as octal.
My vote is for the ...toString().length() method!

Subject: [PJUG Javamail] OT: Formula For Determining # Of Digits In An
Integer


Hi,

I know many of you folks are advanced in mathematics.  I need a formula that
will take an integer and return the number of its digits:

3	--> 1
25	--> 2
52341	--> 5
032	--> 2 (ignore leading 0's)

Any ideas?

--Jason
