Java: How to check if a double has a decimal potion?

[statik213]

I'm doing this right now:

double d;

if(d > (long) d)
// has a decimal potion
else
// is an integer

is there a better a way?

I would have done this:

double d;
if((int)d == d){
//stuff
}
else{
//other stuff
}

Your code doesn't work with negative numbers.

You can use modulus operator (%) with doubles as well.

double d;
if (d % 1.0 > 0)
// We have decimal part.
