ELI5: How does the existence of irrational numbers help in disproving the 'we're living in a simulation' hypothesis?

I think the idea is that to store an entire irrational number, you would need an infinite amount of memory.  Numbers like Pi never end, so you would end up in a situation where Pi has more digits than there are atoms in the universe.

However, there are *algorithms* that can be used to calculate irrational numbers to a certain degree of precision.  If we were in a simulated universe, it could just calculate that number to whatever precision is required at that time.
