Computes the floating-point remainder.

    Format

      #include  <math.h>

      double fmod  (double x, double y);

      float fmodf  (float x, float y); (Integrity servers, Alpha)

      long double fmodl  (long double x, long double y);
                         (Integrity servers, Alpha)

1 - Arguments

 x

    A real value.

 y

    A real value.

2 - Description

    The fmod functions return the floating-point remainder of the
    first argument divided by the second. If the second argument is
    0, the function returns 0.

3 - Return Values

    x                  The value f, which has the same sign as the
                       argument x, such that x == i * y + f for some
                       integer i, where the magnitude of f is less
                       than the magnitude of y.
    0                  Indicates that y is 0.
