cosh

function

Library: Trigonometry (OMTRIG)
Import : omtrig.xmd

Returns: the hyperbolic cosine of a floating point number


Declaration 
export external float function
     cosh value float x


Purpose

Use cosh to calculate the hyperbolic cosine of a floating point number. This trigonometric function works the same way as its equivalent in the C math library.

Out-of-range values return infinity, "+ INF".

Example:


  import "omtrig.xmd" unprefixed
  import "omfloat.xmd" unprefixed
  process
     local float x initial {45}
     local float cosh-value
     set cosh-value to cosh x
     output "Hyperbolic cosine of x, where x = "
         || "d" % x
         || ", is "
         || "d" % cosh-value
         || "%n"
  ; Output: "Hyperbolic cosine of x, where x = 45, is 17467135528742610000"
