I think a program like QPI is not what the OP is looking for. QPI tries to approximate a given number by a fraction or a term with logs and roots. This can be misleading. For instance, when set to 6 digit precision such a program may return "pi" even if the result of a calculation is simply 355/113 – and vice versa. The idea is not to have a number and then find a "nice" representation for it, but to display the exact result of a calculation (which can then be evaluated as a decimal approximation).

Also consider that QPI would return the result of √(3²+4²) simply as "5" and not as √25. ;-)
