Simple typed virtual machine in C++

Abstract VM - Simple typed virtual machine in C++

Implements five number types: three integer types or 1, 2, and 4 byte widths, and two floating point types of 4 and 8 byte widths. Features a simple precision promotion model, if an float and a double are added the result will be a double. Implemented in C++11 making use of..
class templates, class specialization, abstract virtual classes and custom exceptions.
