Mathematical Library Functions remainder(3M)
NAME
remainder, remainderf, remainderl - remainder function
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include
double remainder(double x, double y); float remainderf(float x, float y);long double remainderl(long double x, long double y);
DESCRIPTION
These functions 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| = 1/2, the value
n is chosen to be even. The behavior of remainder() is independent of the rounding mode.RETURN VALUES
Upon successful completion, these functions return thefloating point remainder r = x - ny when y is non-zero.
If x or y is NaN, a NaN is returned.If x is infinite or y is 0 and the other is non-NaN, a
domain error occurs and a NaN is returned.ERRORS
These functions will 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_ERREXCEPT) is non-zero, then the
invalid floating-point exception is raised.
The remainder() function sets errno to EDOM if y argument is 0 or the x argument is positive or negative infinity.SunOS 5.11 Last change: 12 Jul 2006 1
Mathematical Library Functions remainder(3M)USAGE
An application wanting to check for error situations can set errno to 0 before calling remainder(). On return, if errnois non-zero, an error has occurred. The remainderf() and
remainderl() functions do not set errno.
