NAME
       PDL::Constants -- basic compile time constants for PDL

DESCRIPTION
       This module is used to define compile time constant values for PDL.  It
       uses the constant module for simplicity and availability.  We'll need
       to sort out exactly which constants make sense but PI and E seem to be
       fundamental.

SYNOPSIS
	use PDL::Constants qw(PI E);
	print 'PI is ' . PI . "\n";
	print 'E  is ' .  E . "\n";

   PI
       The ratio of a circle's circumference to its diameter

   DEGRAD
       The The number of degrees of arc per radian (180/PI)

   E
       The base of the natural logarithms or Euler's number

   I
       The imaginary unit, " I*I == -1 "

   J
       The imaginary unit for engineers, " J*J == -1 "
