I don't think that repo up to date. The current PDL CPAN devel release has
this to say:
pdldoc Constants
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

Which one PDL use for trig functions : radians or degrees
And is there functions for conversion ?
The docs is very terse on this ...
There is some constant mentioned in PDL::Constants DEGRAD, but I dont
see it in the source.
