Indeed, this is not that out of the ordinary.

I heard tonight that they use python for their backend. (+1 over the php using mtgox)

So the are most likely using the Decimal data type from the standard lib. This is not strange.

What I think should happen is crap like this should be removed as soon as it is realized it is crap. You are tarnishing the name of a business.

Or the OP should have contacted TradeHill with their little 'discovery' before pulling this.

How many scrolled through the forums, saw "TradHill API was coded by amateurs" without taking the time to find out the truth?

That sentiment is now floating around in their subconscious.
