SYNOPSIS

12       float sinf(float x);
13       long double sinl(long double x);

DESCRIPTION

25       The sin() function returns the sine of x, where x is given in radians.
26

RETURN VALUE

28       On success, these functions return the sine of x.
29
30       If x is a NaN, a NaN is returned.
31
32       If x is positive infinity or negative infinity, a domain error  occurs,
33       and a NaN is returned.
34

ERRORS

36       See  math_error(7) for information on how to determine whether an error
37       has occurred when calling these functions.
38
39       The following errors can occur:
40
41       Domain error: x is an infinity
42              errno is set to EDOM (but see BUGS).  An invalid  floating-point
43              exception (FE_INVALID) is raised.
44

CONFORMING TO

46       C99, POSIX.1-2001.  The variant returning double also conforms to SVr4,
47       4.3BSD, C89.
48

BUGS

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