Float Mod Function

[Clyde]

Has anyone made an mod or % ( modulous ) function that returns a float or int like in Blitz and FREEBasic and that copes with negatives too, I dont think fmod is the answer. Or could you help me in creating one please?

example:
If ( float_variable mod 1.0>=0.5 ) then
{
....;
....;
}
end if

another example:
if ( a mod 360 ) then .....

Cheers,
Clyde.

What exactly do you expect modulo to return on negative input?

You're probably looking for something like this:

Code: [Select]

float modulo(float v, float max)
{
   float p= fmod(v, max);
   if (p<0.0)
      p+=max;
   return p;
}
