Library: Trigonometry (OMTRIG) Import: omtrig.xmd

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

Declaration

export external float function
     cosh value float x

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"
