ATOF(III) 4/30/73 ATOF(III) NAME atof - convert ASCII to floating SYNOPSIS double atof(nptr) char *nptr; DESCRIPTION Atof converts a string to a floating number. Nptr should point to a string containing the number; the first unrecognized character ends the number. The only numbers recognized are: an optional minus sign followed by a string of digits optionally containing one decimal point, then followed optionally by the letter e followed by a signed integer. DIAGNOSTICS There are none; overflow results in a very large number and garbage characters terminate the scan. BUGS The routine should accept initial +, initial blanks, and E for e. Overflow should be signalled.
