App Description

This computer program is used to convert numbers among decimal, hex, binary and gray code. If a user changes any one of these numbers, the other ones will change accordingly. It is a handy calculator for engineers to obtain the binary or gray code values from a decimal, or vise versa.
In addition, an animated solution of a Hanoi Tower with three disks is also demonstrated based on the input number.
