Except that precision isn't decimal place. Don't most apps in the real (pun intended) world use six digit precision? UV has a max of 14, no? iirc INFORMATION had arbitrary precision, but then they did provide specialised microcode to do BCD ... I once got a load of kudos by showing my colleagues how to replace an error-prone case statement with a couple of lines of provably correct code to output figures to four significant places. Proved incredibly useful when they brought in the EMS - who remembers the six-digit fixed exchange rates? But when you're working with currencies, from Pounds Sterling where many prices are in pence, through Italian or Turkish Lire where they are in thousands or millions, to hyper-inflated messes like Zaire where all bets are off ... displaying to four digits can be tricky ...
