Ever wondered how to calculate a given number?

How you ever wondered what is special about your favourite number? As we all know, the answer to the ultimate question of life, the universe and everything is \(42 = 2100/50 \approx sin(\pi 3/26)-sin(\pi 11/39)\) and can also be approximated very well by many other expressions.

By using the The Inverse Symbolic Calculator (ISC) you can take numerology to another level by finding closed expressions that well approximate the number (any truncated decimal) you think has some special meaning. It used a mixture of lookup tables and integer relation algorithms. The tables were first compiled by S. Plouffe.

Whatever you do please have some fun with it.
