I did not only describe it, I tested it. I just "tricked" a bit. You asked to extract the last two digits, and I used "% 100" to do this. Note that this works correctly in any number base - may it be 10 or 16 or whatever :-)
Hey, that was clever, wasn't it? :-)
yeah it was - but of course I really wanted the next 2 digits as well.... I'm hoping to make more than 100 units really! pardon me for over-simplifying my question.
I wonder if it would be useful/helpful to allow the user to optionally over-ride the number base for reading and separately for writing by setexpr.
That would extend it's usefulness without requiring an extra command or breaking any existing code
say
setenv setexpr_in 10 setenv setexpr_out 16
If I wrote a patch would you look favourably on it?
