Line 91: ==Implementations== Octuple precision is rarely implemented since usage of it is extremely rare. [[Apple Inc.]] had an implementation of addition, subtraction and multiplication of octuple-precision numbers with a 224-bit [[two's complement]] significand and a 32-bit exponent.<ref>{{cite web\|url=http://images.apple.com/ca/acg/pdf/oct3a.pdf \|title=Octuple-precision floating point on Apple G4 (archived copy on web.archive.org) \|author1=R.
