i ran into the problem where my program would sometimes be forced to take negative square roots. I tried to catch an error somewhere in the function, but couldn't do so.
I've tried the following:

`eval { $number = sqrt(-1) };
if ($@) { print "negative sqrt"; }
`

and

`$number = sqrt(-1) or die "error";
`

and

`$number = sqrt(-1) or print "error";
`

all with no luck. Math::Complex manages to take negative squareroots, but i didn't wanna bother doing that. The only good solution i can come up with right now is checking for a negative number before performing the function. Any ideas on alternatives?
