acos value float x
A trigonometric function that calculates, in radians, the arc cosine (inverse cosine) of a floating point number. This function works the same way as its equivalent in the C math library.
Out-of-range values, (|x| > 1), return "not a number" (NaN).
Example:
;
include "omtrig.xin"
process
local float x initial {0.567}
local float acos-value
set acos-value to acos x
output "Arc cosine of x, where x = "
|| "d" % x
|| ", is "
|| "d" % acos-value
|| ",%n"
; Output: "Arc cosine of x, where x = 0.567, is 0.967937080405776"
