Form num width precision
(Form aword width)
the first form outputs a word containing a printable representation of "num", possibly preceded by spaces (and therefore not a number for purposes of performing arithmetic operations), with at least "width" characters, including exactly "precision" digits after the decimal point. (If "precision" is 0 then there will be no decimal point in the output.)
As a debugging feature, (FORM num -1 format) will print the floating point "num" according to the C printf "format", to allow
to hex :num
op form :num -1 "|%08X %08X|
to allow finding out the exact result of floating point operations. The precise format needed may be machine-dependent.
The second form outputs a new word containing the truncated aword with as many spaces appended to it to make it have width number of characters.
