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
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.
