Some more fun with this...
If a bit less = one bit less, then you may have the following outcomes:
1) Right shift the binary representation of the number by one. That cuts it in half (500000). Of course then we don't know the currency yet, but 500000 Iranian Rials come out to $14.19 US Dollars (according to Google as of me typing this).
2) Drop the first bit (left most) and the resulting number is 475712. The US Dollar amount changes to $13.50.
3) Or you could just take any bit out, but the above two reduce the original amount the most.
And one wonders why contracts get so wordy.
