README for Math-TotalBuilder This module provides two subroutines, build and total, which can be used to handle quantities of valued items. These can be used to build the proper tender to represent a quantity of money, to compose a mass from standard weights, to convert a difference of seconds to a set of time units, or other similar calculations. use Math::TotalBuilder; my %lsd = ( pound => 240, shilling => 20, penny => 1 ); # units for 952 pence my %tender = build(\%lsd, 952); # total value of 3, 21, 98 my $wealth = total(\%lsd, { pound => 3, shilling => 21, penny => 98 }); # best better representation of 18, 6, 40 my %moolah = build(\%lsd, total (\%lsd, { pound => 18, shilling => 6, penny => 40 }));
