CI numeric variables only handle integers (whole numbers).  If your answer
needs to be expressed with a decimal value (like 148.17 as shown above) you
might be able to do something to express it as a string to the CI (setvar
string_x "!x").

This is really sounding like something that's best handled by another
solution -- like a compiled program or maybe a perl script.

fwiw, the perl bundle that's available from Allegro has the MPE extensions
included.  This means you could do take advantage of perl's 'getoptions' as
well as 'hpcicmds' (if you really need to get your result available at the
CI level...)      - d
