Sin ( NUMBER )

This function takes a numeric value and returns the trigonometric sine of it. The input value is assumed to be in radians. The input value is interpreted as a floating-point number.

	a = sin(0);            // a = 0.0
	a = sin(pi() / 2);     // a = 1.0
	a = sin(pi());         // a = 1.2E-16 (float rounding - close to 0)
	a = sin(3 * pi() / 2); // a = -2.4E-16 (float rounding - close to 0)
	a = sin(2 * pi());     // a = -1.0

The return value of this function relies on TAME's implementation of Sine, which may be slightly different between implementations.

Due to rounding issues, you may be better off epsilon-rounding the return value, as some results that should be 0 may be nonzero, but very small.
