ATOF(3) ATOF(3) NAME atof, atoi, atol - convert ASCII to numbers SYNOPSIS double atof(nptr) char *nptr; atoi(nptr) char *nptr; long atol(nptr) char *nptr; DESCRIPTION These functions convert a string pointed to by nptr to floating, inte‐ ger, and long integer representation respectively. The first unrecog‐ nized character ends the string. Atof recognizes an optional string of spaces, then an optional sign, then a string of digits optionally containing a decimal point, then an optional ‘e’ or ‘E’ followed by an optionally signed integer. Atoi and atol recognize an optional string of spaces, then an optional sign, then a string of digits. SEE ALSO scanf(3S) BUGS There are no provisions for overflow. 7th Edition May 15, 1985 ATOF(3)
