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

Return type: opaque Returns: The cosine of a floating point number.

Declaration

define external float function
     cos value float x

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"
