Library: omtrig - trigonometry
Include: omtrig.xin |
Return type: OMX Returns: The arc tangent of a floating point number. |
define external float function
atan value float x
Use atan to calculate, in radians, the arc tangent of a floating point number. (The arc tangent is the inverse of the tangent.) This trigonometric function works the same way as its equivalent in the C math library.
Example:
include "omtrig.xin"
process
local float x initial {90}
local float atan-value
set atan-value to atan x
output "Arc tangent of x where x = "
|| "d" % x
|| " is "
|| "d" % atan-value
|| "%n"
; Output: "Arc tangent of x where x = 90 is 1.559685672897289"
