For math lovers

The coolest PC utility I've seen in ages is a replacement for the wimpy Windows Calculator. It's called Virtual Calc 2000 and it's pretty amazing. From the author's web site:

It supports "infinite" (2,147,483,645) digits (at arbitrary precision). To give you an example of how BIG 10^2147483645 is...

• Number of books in Library of Congress: 10⁸
• Number of people in the world: 10⁹
• Number of particles (smaller than atoms) in universe: 10⁷⁹

It also supports unconstrained bases. YES! UNCONSTRAINED. That means you are no longer limited by the common bases (binary, octal, decimal, and hexadecimal). Virtual Calc supports ANY base from 2 on up. Try base 3, 4, 5, 20, 30, 40, 50, or ANY base you desire! No limits!!

It also supports "decimal" point, "binary" point, "hexadecimal" point, "octal" point, and ANY floating point from base 2 and up. Did you know that all the calculators in the world support ONLY the decimal point? Virtual Calc FREES you from this constraint! Calculate floating point numbers in ANY base you choose! 2, 3, 4, 38, 64, etc. NO constraints!

It also supports infix expressions. Do you hate it when you are calculating a lot of numbers, and have to start over if you make a mistake? With Virtual Calc, you can type the whole expression (77.632 + (55/0.41) * 333 - 2222.3 + 888 - 12345.67 * (987 + 345)) BEFORE you calculate. You can then go back and modify a few numbers, punch calculate to see the results instantly! No retyping!

It also supports customizable symbols for ALL digits of ANY base, and ALL arithmitic operators!! Example, you can customize digits 1234567890 to abcdefghij, and + - * / to ! @ # $, or ANY symbols you desire. Afterwards, if you input abc!def, Virtual Calc will output egi. (123+456=579) Virtual Calc frees you from symbolic constraints!

Virtual Calc is FAST! So fast, it will shock you. Try Adding, Subtracting, Multiplying, Dividing 100,000+ digit numbers. No kidding. Compare it with others when calculating large numbers.

The author has also written a paper on encryption called "Base Encryption" featuring a very intriguing demonstration of encrypting messages using Virutal Calc.

Virtual Calc 2000 is free for the basic version (base conversion up to base 64). The full version is $20 and gives you unlimited base conversions and more math functions. Highly recommended.
