# sinf(3m) [opensolaris man page]

```sin(3M) 						  Mathematical Library Functions						   sin(3M)

NAME
sin, sinf, sinl - sine function

SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include <math.h>

double sin(double x);

float sinf(float x);

long double sinl(long double x);

DESCRIPTION
These functions compute the sine of its argument x, measured in radians.

RETURN VALUES
Upon successful completion, these functions return the sine of x.

If x is NaN, a NaN is returned.

If x is +-0, x is returned.

If x is +-Inf, a domain error occurs and a NaN is returned.

ERRORS
These functions will fail if:

Domain Error    The x argument is +-Inf.

If  the	integer  expression  (math_errhandling & MATH_ERREXCEPT) is non-zero, then the invalid floating-point exception is
raised.

USAGE
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before  calling	these  functions.  On  return,	if
fetestexcept(FE_INVALID	|  FE_DIVBYZERO  |  FE_OVERFLOW  |  FE_UNDERFLOW) is non-zero, an exception has been raised. An application should
either examine the return value or check the floating point exception flags to detect exceptions.
