Inside Macintosh: PowerPC Numerics
This document is the reference for the PowerPC Numerics environment. The document defines data formats for floating-point arithmetic and describes functions you can use to evaluate expressions, convert between formats, and perform standard and transcendental math. Inside Macintosh: PowerPC Numerics also describes the basics of the floating-point architecture in PowerPC assembly language.

Appendix A describes how PowerPC Numerics differs from the Standard Apple Numerics Environment (SANE) and explains how to convert programs that use SANE features to use PowerPC Numerics features instead.
