# DTOR()

Convert degree to radiant

Syntax

  DTOR (nDegree) -> nRadiant

Arguments

  <nDegree> the size of that angle in degree

Returns

  <nRadiant> the size of an angle in radiant

Description

  The function DTOR() can be used to convert sizes of angles given in degrees to radiant (as expected by sin, cos or tan functions).

Examples

          ? dtor (180) --> PI()
          ? dtor (60) --> PI()/3
    Tests
          dtor (0.0) == 0.0
          dtor (180.0) == PI()

Status
