[Classification]

Mathematical library

[Syntax]

#include <math.h>

long double __far sinl(long double x); (C99)

[Return value]

Returns the sine of x.

If x is Not-a-Number or ±∞, sinl returns a Not-a-Number (NaN) and sets macro EDOM to global variable errno.

If the solution is a denormal number, sinl sets macro ERANGE to global variable errno.

[Description]

This function calculates the sine of x. Specify the angle in radian.
