float       fmodf( float x, float y );
(since C99)
double      fmod( double x, double y );
long double fmodl( long double x, long double y );
(since C99)

Computes the remainder of the division operation x/y.

Specifically, the returned value is x - n*y, where n is x/y with its fractional part truncated.

The returned value will have the same sign as x.

[edit] Parameters

x, y - floating point values

[edit] Return value

Remainder of dividing arguments. The returned value will have the same sign as x.
