Math::SigDig version 1.0
========================
SigDig.pm
Version 1.0
What is it?
-----------
Math::SigDig is a module that provides methods to round a number to a
specified number of significant digits and count the number of significant
digits. It allows you to edit numbers to a significant number of digits
(whether they include a decimal point or not). In scientific endeavors, the
number of digits that are "significant" in the result of a calculation using
2 numbers is frequently the number of significant digits in the number with
the least number of significant digits (e.g. 2.0 * 232.12 = 464.24, where
464.24 is reduced to 2 significant digits: 460).
