**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";PIThe ratio of a circle's circumference to its diameterDEGRADThe The number of degrees of arc per radian (180/PI)EThe base of the natural logarithms or Euler's numberIThe imaginary unit, " I*I == -1 "JThe imaginary unit for engineers, " J*J == -1 "
