NAME
atof - convert a string to a double
SYNOPSIS
#include <stdlib.h>
double atof(const char *nptr);
DESCRIPTION
The
atof()
function converts the initial portion of the string
pointed to by nptr to
double.
The behavior is the same as
strtod(nptr, NULL);
except that
atof()
does not detect errors.
RETURN VALUE
The converted value.
ATTRIBUTES
Multithreading (see pthreads(7))
The
atof()
function is thread-safe with exceptions.
It can be safely used in multithreaded applications, as long as
setlocale(3)
is not called to change the locale during its execution.
CONFORMING TO
