You’ll sometimes have to use the notion of infinity in your Ruby code. There isn’t any way to directly use infinity in Ruby, at least none that I know of… But there’s a tip to get it.
Let’s say that you have a
next_row method which has to return next line of an infinite array – rows are added on the fly by another process.
In practice you’ll certainly use
#loop but we’re going to use
#each for the sake of demo.
A quick test in IRB tells use that
1.0 / 0.0 is interpreted as
Infinity directly without this trick you can use:
#each implementation will loop forever. It’s definitively not the right solution to loop over elements but I thought it was interesting to know this little Ruby secret.
