yep,

Sort of. I think I just mis-read my comparison (got confused coz I was using guess and next guess...)

Change this: 

while (abs($num - $guess**2) > 1e-13) {

[download]
to the more accurate comparison (with 2 more decimal places of accuracy): 
while (abs($num/$guess - $guess) > 1e-15) {

[download]
and it works fine :)
