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.
