Dollaes and cents and decimal arithmetic.
If you are doing calculations on dollars and cents ie $10.11, $20.61
and you want precise results to the penny, even after extensive
manipulation of the numbers then do the following
income11=income1+20; /* adding 20 pennies instead of adding 0.20
income22=income2+20; /* adding 20 pennies instead of adding 0.20
/* at the very end convert to dollars */
if dif=50 then do;
put dollars 5.2;
