How many random numbers do you need {drivel} {drone}

Not many. My first guess:

$x = 1.000000001; say abs($x**1e8);; 1.10517092716461 $x = 1.000000001; say abs($x**(1e8+1));; 1.10517092826979

You seem to have missed: "semi-random range" & "well-chosen set of inputs". Inspecting a string for exponentiation by big constants is trivial.

if you consider replying that you limit the range as soon that one function returns inf think about functions with multiple separated intervals ...

Vary them one at a time...

I'd rather avoid ...

You are quite welcome to do things the hard way; it seems to suite.

The OP asked for ideas.


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

    [Eily]: you could tie a variable into not having the same value each time, if you like to make people who try to debug your code facepalm
    [Corion]: perl -wle 'package o; use overload q("") => sub {warn "str"; ""}, bool => sub{warn "bool"; 1}; package main; my $o={}; bless $o => o; print "Yay" if ($o && !length($o))'
    [Corion]: But people writing such code should document the objects they construct and why it makes sense for an object to be invisible as string while being true in a boolean context
    [hippo]: That's equal parts clever and horrendous.
    [Eily]: the overload version wouldn't return true with "$x" && !length $x though, I guess
    [hippo]: The more I look at this code, the more $x is a plain old scalar and the more this condition will never be true. I'm calling it a bug at this point.
    [hippo]: Thanks for your input which has soothed my sanity (a little)
    [Corion]: Eily: Sure - if you force both things into stringy things, then you break that magic. But that would also mean that you changed the expression, as now $x = 0.00 will be true instead of false as it were before
    [Corion]: Ah no, at least in my feeble experiments that doesn't change the meaning
    [Corion]: We sell sanity in small packages ;)
