PowerPC Numerics" by Apple Computer, Inc. covers the IEEE standard numerics environment and the Mac OS X numerics C implementation.

Key topics include IEEE standard arithmetic, floating-point data formats, environmental controls, conversions, and numeric operations and functions. The book also discusses the implementation of these concepts in C, including numeric data types, environmental control functions, conversion functions, and transcendental functions.

The IEEE standard numerics environment is based on the IEEE 754 floating-point standard, which provides a set of rules for representing and manipulating floating-point numbers. The standard includes features such as careful rounding, exception handling, and support for special values like infinities and NaNs (Not a Number).

The book covers various aspects of the IEEE standard, including:

Floating-point data formats, such as single and double formats
Environmental controls, such as rounding direction modes and exception flags
Conversions between different data formats, including floating-point to integer and integer to floating-point
Numeric operations and functions, including comparisons, arithmetic operations, and transcendental functions

The Mac OS X numerics C implementation provides a set of functions and data types for working with numbers in C programs. The implementation includes support for the IEEE standard numerics environment and provides a range of functions for performing numeric operations, including:

Numeric data types, such as float, double, and long double
Environmental control functions, such as setting the rounding direction and accessing the floating-point environment
Conversion functions, such as converting between floating-point and integer formats
Transcendental functions, such as exponential, logarithmic, and trigonometric functions.

Overall, the book provides a comprehensive overview of the IEEE standard numerics environment and the Mac OS X numerics C implementation, and is intended to assist developers in creating applications that require precise and efficient numeric computations.
