How do you get the last two didgets of a number?

How do you get the last two didgets of a number? If I have a number x=390 how do I get a y so that y-90 for an arbitrary case?
I know that if you multiply x by .01 you can get the desired didgets into a decimal, but I don't know if that helps.

ie: 390*.01=3.90

{
%lastdigits = %num - (floor(%num/100) * 100);
return %lastdigits;
}

Function lastdigits(%num){
%lastdigits = %num - (floor(%num/100) * 100);
return %lastdigits;
}

Your a genuis harold, nice to see you again, and thanx for the tip
#4
i = num % 100; //(returns number 0 - 100)
in both C++ and torque script

Modulus (remainder) should work too:i = num % 100; //(returns number 0 - 100)
in both C++ and torque script

Hmm... thinking about it... this would be a much better function:
This will either give you the number of digits you specify or everything except the first digit.

Yep, that would be much simpler.Hmm... thinking about it... this would be a much better function:
function lastdigits(%num, %places)
{
if(%places > 0)
%pow = %places;
else
%pow = strlen(%num)-1;
%result = %num % mPow(10,%pow);
return %result;
}This will either give you the number of digits you specify or everything except the first digit.

Im using the lastDidget function that you first posted Harold, and it seems to work fine. Don't need anything too much fancier. Neat trick though Pascal

I modified Harold's original Function:
ie.
echo(lastdigits(10.77));
returns 0.77
echo(lastdigits(-10.77));
returns 0.23
if return value > 0 && return value < 1
It's a decimal.

I guess I misunderstood the question. I was looking find if a number was a decimal.I modified Harold's original Function:
function lastdigits(%num)
{
%lastdigits = %num - (mfloor(%num));
return %lastdigits;
}ie.
echo(lastdigits(10.77));
returns 0.77
echo(lastdigits(-10.77));
returns 0.23
if return value > 0 && return value < 1
It's a decimal.
