A LONG time ago (pre-Windows), I wrote a number of programs using Turbo Pascal - one was for working out parallel resistors, you told it just the value you wanted, and it displayed a list of suitable preferred values (in order), and the percentage of error for each combination.
Unfortunately all the programs were on a long dead 386 laptop!
But in any case, it was pretty easy to write.
