function
Returns: the sine of a floating point number
define external float function sin value float x
Use sin to calculate the sine of an angle in radians. The angle must be a floating point number. This trigonometric function works the same way as its equivalent in the C math library.
The following sample shows how to use sin to calculate the value of the sine of PI/2. The result is 1.00.
include "omtrig.xin" process output "The sine of (pi/2) is " || "d" % (sin (pi / 2)) || " %n" ; Output: "The sine of (pi/2) is 1"
