ATOF(III) 4/30/73 ATOF(III)
NAME
atof - 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.
