Inside Macintosh: PowerPC Numerics / Part 2 - The PowerPC Numerics C Implementation

Chapter 9 - Conversion Functions

This chapter describes how you can perform the conversions required by the IEEE standard using MathLib C functions. For each type of conversion, this chapter lists the functions you can use to perform that conversion. It shows the declarations of these functions, describes what they do, describes when they raise floating-point exceptions, and gives examples of how to use them. For a description of the conversions required by the IEEE standard and the details of how each conversion is performed in PowerPC Numerics, see Chapter 5, "Conversions." All of the conversion function declarations appear in the file fp.h.
