Library: omtrig - trigonometry
Include: omtrig.xin |
Return type: Opaque 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.
Out-of-range values return "not a number" (NaN).
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"
