Defined in header <cmath>
float       fmod( float x, float y );	(1)
double      fmod( double x, double y );	(2)
long double fmod( long double x, long double y );	(3)
Promoted    fmod( Arithmetic x, Arithmetic y );	(4)	(since C++11)

Computes the remainder of the division operation x/y.

4) If any argument has integral type, it is cast to double. If any other argument is long double, then the return type is long double, otherwise it is double.

Parameters

x, y

-

floating point values

Return value

Remainder of dividing arguments. The result has the same sign as x.
