*Compute the floating point remainder*

#include <math.h> double remainder( doublex, doubley); float remainderf( floatx, floaty); long double remainder( long doublex, long doubley);

*x*- The numerator of the division.
*y*- The denominator.

These functions return the floating point remainder
*r* = *x* - *n**y*, where *y* is nonzero.
The value *n* is the integral value nearest the exact value *x*/*y*.
When |*n* - *x*/*y*| = ½, the value *n* is chosen to be even.

The behavior of *remainder()* is independent of the rounding
mode.

The floating point remainder *r* = *x* - n*y*,
where *y* is nonzero.
If *x* is infinite or *y* is zero and
the other is non-NaN, these functions return NaN.

If an error occurs, these functions return 0, but this is also a valid
mathematical result.
If you want to check for errors, set
errno
to 0, call the function, and then check errno again.
These functions don't change errno if no errors occurred. |
