IIRC there was a programmer working for a bank that managed to siphon off the 
sub-unit fractions that the interest calculating software generated (how much 
interest is owed for $10000 at 0,25% p.a. for 2 days*) onto his own account and 
temporarily got rich quick.

$10000 * 0,25% = $25 (interest for 1 year)
$25 * 2 / 360 = $0,13888889 (interest for 2 days)

This is split into 13 cents for the client and nearly 0,9 cents that the bank 
keeps

But he's using the field to store an amount of money in.  So why ask for 
anything with ten places after the decimal point ?  No genuine currency 
requires more than three places.
