NAME

       sin, sinf, sinl - sine function

SYNOPSIS

       #include <math.h>

       double sin(double x);
       float sinf(float x);
       long double sinl(long double x);

       Link with -lm.

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       sinf(), sinl():
	   _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
	       || /* Since glibc 2.19: */ _DEFAULT_SOURCE
	       || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION

       These functions return the sine of x, where x is given in radians.

RETURN VALUE

       On success, these functions return the sine of x.

       If x is a NaN, a NaN is returned.

       If x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned.

ERRORS

       See math_error(7) for information on how to determine whether an error has occurred when calling these functions.

       The following errors can occur:

       Domain error: x is an infinity
	      errno is set to EDOM (but see BUGS).  An invalid floating-point exception (FE_INVALID) is raised.

CONFORMING TO

       C99, POSIX.1-2001, POSIX.1-2008.

       The variant returning double also conforms to SVr4, 4.3BSD, C89.

BUGS

       Before version 2.10, the glibc implementation did not set errno to EDOM when a domain error occurred.
