What is the allowed format for PayPal's Website Payments Standard (WPS) forms in the "amount" field? Must the decimal point be ".", or is it currency-dependant? Must there always be exactly two decimal places, or can there also be three (for currencies that have such small nominations) or none (for currencies that have hyper-inflation)?
I know that this should be a question for PayPal's documentation/forums, but the first has a vast room for improvement (to say the least) and the second is as speedy as a sleeping snail. I have posted a question there, but I don't expect any replies sooner than about two weeks. Hopefully someone here will have an idea.
