Class: Dicey::NumericDie

Inherits:
AbstractDie show all
Defined in:
lib/dicey/numeric_die.rb

Overview

A die which only has numeric sides, with no shenanigans.

The only inherent difference in behavior compared to AbstractDie is that this class checks values for sides on initialization. However, other classes may reject AbstractDie even with all numeric sides.
