As said: random numbers are a matter if taste (or of the application)

e.g. :

I once did a project where we such a wide range of integer random 
numbers that doing them as int64 was not enough

With "Monecarlo" method to estimate  statistical profitability you 
usually need random numbers as real-values to enter them in a simulated 
process. here predictability is not a great issue.

Cryptography is a completely different issue. here a decent device uses 
hardware to create the random seed.
