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

Chapter 10 - Transcendental Functions

This chapter describes how to use the transcendental and auxiliary functions declared in MathLib. This chapter describes the following types of functions:

• comparison
• sign manipulation
• exponential
• logarithmic
• trigonometric
• hyperbolic
• financial
• error and gamma

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 functions that manipulate the floating-point environment, see Chapter 8, "Environmental Control Functions." For functions that perform conversions, see
Chapter 9, "Conversion Functions." For basic arithmetic and comparison operations,
see Chapter 6, "Numeric Operations and Functions."

Some transcendental functions have two implementations: double precision and double-double precision. The double-double-precision implementation has the letter l appended to the name of the function and performs exactly the same as the double version. This book uses the double-precision implementation's name to mean both of these implementations. All of the transcendental function declarations appear in the
file fp.h.
