remainder (3p) - Linux Man Pages
remainder: remainder function
PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
remainder, remainderf, remainderl - remainder function
These functions shall return the floating-point remainder r= x- ny when y is non-zero. The value n is the integral value nearest the exact value x/ y. When |n-x/y|=0.5, the value n is chosen to be even.
Upon successful completion, these functions shall return the floating-point remainder r= x- ny when y is non-zero.
If x or y is NaN, a NaN shall be returned.
These functions shall fail if:
- Domain Error
- The x argument is ±Inf, or the y argument is ±0 and the other argument is non-NaN.
If the integer expression (math_errhandling & MATH_ERRNO) is non-zero, then errno shall be set to [EDOM]. If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, then the invalid floating-point exception shall be raised.
