------------------------------------------------------------------------------

 Syntax

      TANR( <nRadian> ) -> nTan

 Arguments

      <nRadian> is a numeric value representing a radian value.

 Returns

      TANR() returns the tangent value of <nRadian>.

 Description

      TANR() is a trigonometrical function that returns the tangent value of
      a radian.

      For radians, see TAN().

      Accuracy is to the twelfth decimal (i.e. .00000000001)

 Examples

      ? Str( TANR( 1), 12,  9)  // returns  1.557407725
      ? Str( TANR(-1), 12,  9)  // returns -1.557407725
