Calculate Standard Deviation in a SLC-5/04 ?

Calculate Standard Deviation in a SLC-5/04 ?

(OP)
Has anybody ever programmed rungs of ladder logic in a SLC-5/04 to calculate the Standard Deviation of a data set in an integer file?

There is no point in "re-inventing the wheel" if someone has a good example.

It is EASY in VB, C++, Matlab, Labview, even Excel, but using ladder logic limited to a very simple compute (CPT) instruction is cumbersome at best.
