Library: Math - trigonometry (OMTRIG) legacy Include: omtrig.xin

Return type: OMX Returns:  The tangent of a floating point number.

Declaration

  define external float function
       tan value float x

Use tan to calculate the tangent 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.

Out-of-range values return "not a number" (NaN).

Example:

  include "omtrig.xin"
  process
     output "The tangent of pi/3 is "
         || "d" % (tan (pi / 3))
         || " %n"
  ; Output: "The tangent of (pi/3) is 1.732050807568877"
