cos

function

Library: Trigonometry (OMTRIG legacy)
Include: omtrig.xin

Returns: The cosine of a floating point number.


Declaration 
define external float function
     cos value float x


Purpose

Use cos to calculate the cosine 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.

Example: 

  include "omtrig.xin"
  process
     output "Cosine of x, where x = (pi * 2), is "
         || "d" % cos (pi * 2)
         || "%n"
  ; Output: "Cosine of x, where x = (pi * 2), is 1"
