The bug only seems to manifest itself when I add the sqrt() code. .... To see it go away, comment out the $sqrt definition and change the return statement to return $f.

Sorry Limbic~Region, I do not follow these instructions?

The only definition of $sqrt I can see is     my $sqrt = sqrt( $N );

But I do not understand what you mean by "change the return statement to return $f."?

Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.
