CompSci Calculator lets you calculate in three different bases: decimal, hexadecimal, and binary. CompSci Calculator was developed for programmers, developers, computer engineers, and computer scientists. In real time you can do part of an equation in one base and then switch to another and complete the equation. As you type in any particular base the values in all three modes are displayed together. Because of the real time instant conversion between the bases CompSci Calculator also serves as an excellent conversion tool. Features: -basic algebra between bases -simultaneous answers in all three bases -selectable bit size: 8,16,24,32 -optional additional 16 bits of radix point precision -bitwise functions -1's and 2's complements -shift left and shift right Student and teacher feedback is very appreciated!
