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

NAME
     atof, atof_l -- convert ASCII string to double

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     double
     atof(const char *str);

     #include <xlocale.h>

     double
     atof_l(const char *str, locale_t loc);

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

IMPLEMENTATION NOTES
     The atof() function is not thread-safe and also not async-cancel-safe.

     The atof() function has been deprecated by strtod() and should not be used in new code.

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

STANDARDS
     The atof() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and ISO/IEC 9899:1999 (``ISO C99'').
