sin(3M) Mathematical Library Functions sin(3M)NAME
sin, sinf, sinl - sine function
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include <math.h>
double sin(double x);
float sinf(float x);
long double sinl(long double x);
DESCRIPTION
These functions compute the sine of its argument x, measured in radi‐
ans.
RETURN VALUES
Upon successful completion, these functions return the sine of x.
If x is NaN, a NaN is returned.
If x is ±0, x is returned.
If x is ±Inf, a domain error occurs and a NaN is returned.
ERRORS
These functions will fail if:
Domain Error The x argument is ±Inf.
If the integer expression (math_errhandling &
MATH_ERREXCEPT) is non-zero, then the invalid floating-
point exception is raised.
USAGE
An application wanting to check for exceptions should call feclearex‐
cept(FE_ALL_EXCEPT) before calling these functions. On return, if
fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is
non-zero, an exception has been raised. An application should either
examine the return value or check the floating point exception flags to
detect exceptions.
