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, (char **)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''). BSD
