Prototype

	function sin (
		value  : numeric   
	)

	return_val [dimsizes(value)] :  float or double

Arguments

value

One or more values of any dimension, in radians.

Return value

Returns an array dimensioned the same as value. The return type is double if the input is double, and float otherwise.

Description

This function returns the sine of each element of value. Return values are -1.0 ≤ return_val ≤ 1.0. Missing values are ignored.
