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. ATTRIBUTES
