sin, sinf, sinl - sine function
#include <math.h> double sin(double x); float sinf(float x); long double sinl(long double x);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
These functions return the sine of
x is given in radians.
On success, these functions return the sine of
x is a NaN, a NaN is returned.
x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned.
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.
The following errors can occur:
xis an infinity
errno is set to EDOM (but see BUGS). An invalid floating-point exception (FE_INVALID) is raised.
C99, POSIX.1-2001, POSIX.1-2008.
The variant returning
double also conforms to SVr4, 4.3BSD, C89.
Before version 2.10, the glibc implementation did not set
errno to EDOM when a domain error occurred.
