SANE is the Standard Apple Numerics Engine.

Essentially implements the IEEE floating-point numeric
standard for various Apple computers.  That means for
everything from the Apple II to the Mac.

For anything of Apple's that doesn't have a math coprocessor, this
is the way to get good numerics...a bit slow, perhaps, compared to
a 68882, but you will at least know how correct your math is going
to be, and the degree of error therein.

On the other hand, you *could* look at a 68881/68882 as a SANE
coprocessor...they do pretty much the same job.
