NAME
       PDL::Types - define fundamental PDL Datatypes

SYNOPSIS
	use PDL::Types;

	$pdl = ushort( 2.0, 3.0 );
	print "The actual c type used to store ushort's is '" .
	   $pdl->type->realctype() . "'
";
	The actual c type used to store ushort's is 'unsigned short'

DESCRIPTION
       Internal module - holds all the PDL Type info.  This can be accessed using the "PDL::Type" object returned by the type method.

OBJECTS
       This module declares one class - "PDL::Type" - objects of this class are returned by the type method of a piddle.  It has several methods,
       listed below, which provide an easy way to access type information:

       Additionally, comparison and stringification are overloaded so that you can compare and print type objects, e.g.

	 $nofloat = 1 if $pdl->type < float;
	 die "must be double" if $type != double;

       For further examples check again the type method.

       enum
	   Returns the number representing this datatype (see get_datatype).

       symbol
	   Returns one of 'PDL_B', 'PDL_S', 'PDL_US', 'PDL_L', 'PDL_F' or 'PDL_D'.

       ctype
	   Returns the macro used to represent this type in C code (eg 'PDL_Long').

       ppsym
	   The letter used to represent this type in PP code code (eg 'U' for ushort).

       realctype
	   The actual C type used to store this type.

       shortctype
	   The value returned by "ctype" without the 'PDL_'.
