Infinite.h File Reference

Detailed Description

This file contains the class declaration and implementation for an Infinite object, which adds the values negative infinity and positive infinity to the basic data types int, float, double, and long double.

Most of the basic arithmetic and logical comparison operators are provided. The only thing missing at this point is checking for overflow errors and handling them appropriately.
