HP 12C Permutation and Combination

[Gamo]

Hello Dieter

I try your Permutation and Combination program and found one little problem with the Permutation answer. Most P answer correctly but with this 25P7 I check most calculator result to 2,422,728,000 but on this program result to 2,442,727999 I'm not sure if this result is more accurate or others just round the result up.

Thank You

Gamo
