ATOF(3)                  BSD Library Functions Manual                  ATOF(3)

     atof, atof_l -- convert ASCII string to double

     Standard C Library (libc, -lc)

     #include <stdlib.h>

     atof(const char *str);

     #include <xlocale.h>

     atof_l(const char *str, locale_t loc);

     The atof() function converts the initial portion of the string pointed to by str to double representa-tion. representation.

     It is equivalent to:

           strtod(str, (char **)NULL);

     The decimal point character is defined in the program's locale (category LC_NUMERIC).

     While the atof() function uses the current locale, the atof_l() function may be passed a locale
     directly. See xlocale(3) for more information.

     The atof() and atof_l() functions are thread-safe and async-cancel-safe.

     The atof() and atof_l() functions have been deprecated by strtod() and strtod_l() and should not be
     used in new code.

     The function atof() need not affect the value of errno on an error.

     The atof() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and
