Low-Level Arithmetic Functions

This chapter contains information about functions for doing basic arithmetic operations, such as splitting a float into its integer and fractional parts. These functions are declared in the header file `math.h'.

Not a Number Making NaNs and testing for NaNs.

Predicates on Floats Testing for infinity and for NaNs.

Absolute Value Absolute value functions.

Normalization Functions Hacks for radix-2 representations.

Rounding and Remainders Determinining the integer and
fractional parts of a float.

Integer Division Functions for performing integer
division.

Parsing of Numbers Functions for ``reading'' numbers
from strings.
