This section describes functions for "reading" integer and
floating-point numbers from a string. It may be more convenient in some
cases to use
sscanf or one of the related functions; see
12.14 Formatted Input. But often you can make a program more robust by
finding the tokens in the string by hand, then converting the numbers
one by one.
20.11.1 Parsing of Integers Functions for conversion of integer values. 20.11.2 Parsing of Floats Functions for conversion of floating-point values.
