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 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.
ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────────────────┼───────────────┼─────────┤ │sin(), sinf(), sinl() │ Thread safety │ MT-Safe │ └──────────────────────┴───────────────┴─────────┘
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.
