Inside Macintosh: PowerPC Numerics / Part 1 - The PowerPC Numerics Environment

Chapter 6 - Numeric Operations and Functions

This chapter describes the operations (comparisons, arithmetic operations, and auxiliary and transcendental functions) that PowerPC Numerics allows you to perform on floating-point numbers. Numeric operations are evaluated as floating-point expressions; as such they are affected by, and might affect, the floating-point environment.

Read this chapter to find out what numeric operations are supported and how they work. For more information about how floating-point operations are evaluated in general, see Chapter 3, "Expression Evaluation." For a description of the floating-point environment, see Chapter 4, "Environmental Controls."
