On the other hand, keeping intermediate Doubles to 80-bit precision is both (a) non-portable and (b) unpredictable (the programmer doesn't know which intermediates are going to be stored in 80 bits, and turning on optimisation will probably make a difference).
Indeed, not storing the intermediate values as 80 bits is one of the 'nicer' things I was refering to. :)
though, this does bring up another standardish C type we should support
__float128
and __complex as pointed out by Aaron.
any idea what would be a good module to export them from?
How standard are these? Foreign.C.Types is the obvious place, but it wouldn't be a good idea for that module to contain optional parts of its interface. Cheers, Simon
