I wouldn't even bother testing client implementations that are using floating point numbers to do the math -- they are going to be wrong. If you snoop around you should find math libraries that handle do a better job handling exact numbers for most popular languages.
You'll also need to convince your database interface to use the decimal library you choose, or get it to return 'numeric' types as strings so you can convert them with your chosen library yourself.
It'll do you no good to convert from Pg numeric -> floating point -> exact decimal library format.
