Is there something that's larger than any numbers in PHP?

Question

I need to simulate a ∞ in PHP.

So that min(∞,$number) is always $number.

Answer 1

In Perl you can use

$INF = 9**9E9;

which is larger than any value you can store in IEEE floating point numbers. And that really works as intended: any non-infinite number will be smaller than $INF:

$N < $INF

is true for any "normal" number $N.

Maybe you use it in PHP too?
