Maybe you were thinking of 128 bit long doubles ?

we already use the 128 long doubles, the thing is we do a lot of accounting like
calculations and 'almost accurate' is not an option :-)

Don't use floats or doubles of *any* size for financial applications. See Goldberg's classic paper on the subject:

<http://docs.sun.com/source/806-3568/ncg_goldberg.html>

64 bit integers work great for that matter, but we like to step up to more bits

Don't bother. As Paul said, 64 bit is enough to represent any amount you're going to encounter in real life.
