define external float function 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"
