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( Arithmetic1 x, Arithmetic2 y );
(4) (since C++11)

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.

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.

[edit] Parameters

x, y - floating point values

[edit] Return value

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