RTOD()

Convert radiant to degree

Syntax

      RTOD( nRadiant ) -> nDegree

Arguments

<nRadiant> the size of an angle in radiant

Returns

<nDegree> the size of that angle in degree

Description

The function RTOD() can be used to convert sizes of angles given in radiant (like those returned by the asin, acos or atan function) to degrees that are commonly used geometry and technics.

Examples

      ? rtod( PI() ) // --> 180
      ? tanh( PI() / 3 ) // --> 60

Tests

      rtod( 0.0 ) == 0.0
      rtod( PI() ) == 180.0

Compliance

RTOD() is compatible with CT3’s RTOD().
