Command-Line Calculator

This project contains a command-line calculator. The calculator has one register and five memory cells. It supports about eighty different operators, including add, subtract, multiply and divide. Each operation is printed to the screen. Enter the numbers directly into the Number fields. Use Copy and Paste (Ctrl-C and Shift-Insert) to insert numbers into the Number fields as needed. Use memory cells (M1 - M5) in the Number fields as needed.

Install and Build

The is a C# Console-Mode Project. Open with Visual Studio 2022 and above to compile.

Fields

There are two types of fields: Operator and Number. To see a list of all operators use -ha.

Operator Basics

Type n to save a new number into the base register. Type c to clear the screen and register.

Type mem to view all memory cells. Type sm1 to save the base register into the first memory cell. Type sm2 to save the base register into the second memory cell.

Type m1 to copy the first memory cell into the base register. Type m2 to copy the second memory cell into the base register.

Memory cells can be used in number fields and operator fields. Type m1 to use memory cell one in a calcuation.
