Fix pre-tax unit market price loss of precision

Browse source 
check_trade() converts the price to float, which can lose precision,
although only for ridiculously high prices.  Has been broken since
4.0.0 introduced the market.

Avoid the conversion.  Bulletins now show pre-tax price as $N instead
of $N.00.
