- Update: Base Conversion, Logs, Powers,
Factorials, Permutations and Combinations in JavaScript (27K).
- Fixed a one-off result in combinations for a particular
set of parameters (apparently due to internal operations
on floats instead of ints), by using a somewhat different
evaluation. The error parameters were added to tests,
and all tests pass. But there will inevitably be range
errors for some values, and they may well vary on
different systems.
- Limited integer factorial (done by looping) range to
under 180!, after which it returns -1 error. This makes
it practical to use the method with log results on huge
float values.
- Greatly expanded the range for factorials. On a hand
calculator, 100! is a difficult evaluation, yet even a
small "8-bit" substitution table has 256! arrangements.
A perfect 256-bit-wide block cipher would have (2^256)!
arrangements, which is now a reasonable computation.
