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 xis given in radians.  

RETURN VALUE

On success, these functions return the sine of x.

If xis a NaN, a NaN is returned.

If xis 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
errnois set to EDOM(but see BUGS). An invalid floating-point exception (FE_INVALID) is raised.
 

ATTRIBUTES

CONFORMING TO

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

The variant returning doublealso conforms to SVr4, 4.3BSD, C89.  

BUGS

Before version 2.10, the glibc implementation did not set errnoto EDOMwhen a domain error occurred.
