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

NAME
     atof — convert ASCII string to double

LIBRARY
     Standard C Library (libc, -lc)

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 representation.

     It is equivalent to:

	   strtod(nptr, NULL);

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

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.

SEE ALSO
     atoi(3), atol(3), strtod(3), strtol(3), strtoul(3)

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”).
