Corona Virus Self Isolation Puzzle

Slightly cleaner*, functionally equivalent ST code attached** as btcfb1002.txt.

I'm not saying anything is wrong with the code as is, but I am offering a slightly different approach.


* "Cleaner" is of course a subjective term: the use of the bFound variable causes extra unnecessary evaluations (WHILE/IF and NOT), IMNSHO; then again, the code may be easier for some folks to follow with bFound.


** Along with cvpuzzle.zip of Python-based package that suggests equivalency of the approach: cf. test_cvpuzzle.py; two million pairs of evaluations with random values for [x] produced the same result within each pair.

My original implementation was spread over many cycles of the plc as the scan time was exceeded when using very large numbers for N so I introduced bFound to indicate when the algorithm had completed.

Of course, heh try giving it (x,N)=(1e-4,1e4); so bFound was necessary then.

(unless max allowed scan time is increased outrageously)


It is an interesting algorithm; did tha come up with it th'self or did tha find it?

I found something similar and adapted it for Siemens SCL,
