This lab is using the 32 bit calculator we did in Lab 1 and expanding it by adding a converting a decimal number to Roman Numeral. We use the same process as 1 addition, 2 substraction, 3 multiplication, 4 exponentiation, 5 convert to roman numerals. The system will display a warning message when a value goes over 65536. The Multiplication must be a loop.
