7. This tool uses GMP, the GNU Multiple Precision arithmetic library.
To download this binomial probability calculator, as a standalone program, right-click here (preview), and
“save link as,” or “save target as,” or similar. It is written in Perl, so you'll need to have Perl installed to use it.
On Windows I use 64-bit Strawberry Perl (currently v5.32.0), but most other recent version 5 Perls should
also work. 32-bit Strawberry Perl works, but it's nearly twice as slow.

1 Large values of n make the calculation slower. For example, if
2 Calculating cumulative probablities, rather than a simple binomial probability, makes the calculation slower, especially for large values of k. For example, calculating cumulative probabilities for k=100 requires calculating binomial probabilities for 101 different values of k, and summing them.
3 Long decimal or repeating decimal values of p (or their
equivalents) can make the calculation slower. This mainly affects the “Experimental” precision settings. For example, if
