ATOF(3) BSD Library Functions Manual ATOF(3)NAMEatof, atof_l -- convert ASCII string to doubleLIBRARYStandard 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);DESCRIPTIONThe 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 NOTESThe atof() and atof_l() functions are thread-safe and async-cancel-safe. The strtod() and strtod_l() functions are recommended instead of atof() and atof_l() functions, especially in new code.ERRORSThe function atof() need not affect the value of errno on an error.SEE ALSOatoi(3), atol(3), strtod(3), strtol(3), strtoul(3), xlocale(3)STANDARDSThe atof() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and ISO/IEC 9899:1999 (``ISO C99'').BSDJune 4, 1993 BSD
