Inside Macintosh: PowerPC Numerics / Part 3 - Numerics in PowerPC Assembly Language

Chapter 11 - Introduction to Assembly-Language Numerics

This chapter introduces the numeric implementation in PowerPC assembly language. It describes the basics of the floating-point architecture, showing what floating-point data formats and registers are available, what numeric operations are available in assembly language, and what load and store instructions you must use before you can perform assembly-language numeric operations. An example application using assembly- language numeric operations is shown at the end of this chapter.

Read this chapter to learn how to use the numeric assembly-language instructions described in Chapters 12 through 14.
