A Me Problem Converting String to Long data type
Hi,
I want to do a Math.mod operation on a string (contains numeric values only) in an apex class. The maximul length of the string is 19.
Here is a sample value : 57901220028758151855
The problem is when I try to convert this to Long using Long.valueOf(string) , there is a type exception : invalid long
So I tried to get the long value using : Decimal.valueOf(string).longValue() , but when I check the value using System.debug & it is = 2560987807629497007 , not the same as the original, so the mod result is also not correct.
I have to convert to Int, or Long because those are the only 2 types accepted by Math.mod(). and the max length of Integer is too small for these numeric strings.
The same operation is being performed in a validation rule using MOD (VALUE(string),divisor) with no problems.
Please help.

I want to convert String to Long and keep the numbers as is and not the other way round.

Decimal however truncates the number to fit in 64 bit. That is why you are getting wrong result. Refer to the following link for more information about primitive data types,

Hi,
I was stuck with the same issue, I tried everything and realized that its nothing to do with the Long Class, It is the String value that has been passed, Long.valueOf(Str) doesn't take blank spaces, Try to apply Trim() Method before passing the value. That should resolve the issue.
Thanks
