(19C/29C) (k-)Permutations, Combinations, Linear Regression and Pseudo-random number

[Gene]

Great set of routines!

One suggestion on LBL 5 would be to consider dropping the FIX 2 step.

Another would be to consider getting away from the PI / Y^X generator as they are fairly poor per some tests done in the PPC Journal for getting a good distribution of outputs. Perhaps this?

Saves a step too in case a change elsewhere needs to be made.

But seriously, I love this combination of routines. Makes a great edition to the HP-19C/29C function set.

Once I get my LP HP-29C setup, this will be in memory.
