Is it possible for DBPro to detect a decimal?

do you mean Float variable type?

an integer is like 123
a float is like 123.112233

I was just wondering yesteday if there's a way to determine if a number is real or not. Hmm, I think I could write a quick function.

function isReal(number)
int_number = int(number)
if (number % int_number) = 0 endfunction 0
endfunction 1

The easiest method would be to convert the unknown number to an integer and check to see if it matches the original number.

@ cattleruster: I'll try that

@everyone else: what i want to use it for is pythagorean triples (three integers that work with Pythagoreas' theorm) so i cant check whether it matches the original.

thanks for your help
