And it will be if you carry the monetary amounts in cents, use a floating point format with enough precision, and make appropriate use of rounding to the nearest integer (addition or subtraction of .5 followed by trunc). Bin float(64) is adequate to handle the US budget. So where's the argument? Go back and read what I wrote.

For international financial trasactions you need 5 decimal places of accuracy,
sometimes referred to as 'pips' in the Forex market. Scaled fixed decimal is
the rule of the day here.
