Module: Numeric::BinaryMultipliers

Included in:
Numeric
Defined in:
lib/mega/binary_multiplier.rb

Overview

:title: Binary Multipliers

Mixin for Numeric to make working with bits and bytes easier. These are numerous and therefore provided via a mega-module called BinaryMultiplers, rather then individual nano-methods.
