Linux 2.6 - man page for sinf (linux section 3)

SIN(3)				    Linux Programmer's Manual				   SIN(3)

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():
	   _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE ||
	   _POSIX_C_SOURCE >= 200112L;
	   or cc -std=c99

DESCRIPTION
       The sin() function returns 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.  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.
