Base Calculator - Version 2.2 Base Calculator was specifically for written the computer programmer. It provides a full-featured integer calculator that performs not only the usual operations, such as addition and multiplication, but also the most common logical operations. In addition, Base Calculator understands that computers represent integer numbers using different word sizes. For this reason, Base Calculator provides integer word sizes of 8, 16, 32, 64, 96 and 128 bits, in both signed and unsigned varieties. Base Calculator can display all of these numbers using decimal, hexadecimal, binary and octal representations. The complete, documented source code (written in Borland Delphi) is also supplied as part of the application.
