Yes, unfortunately getFloat() became pretty complex, but that is because

Hello!
[As Larry kindly pointed out to me, I only sent the email to Larry and
not to the mailing list.]
"Alphabet" here still, to me, implies a character set, not a byte stream. Maybe
getBytesFromString? getBytesFromList? getBytesFrom() (because you're getting it "from"

Hi
For completeness, it would be good to have nextBool() as well.
I'm just wondering if that's really necessary. Generating a boolean is
trivial with the nextFloat method (see example 1. Simulate a coinflip
from the RFC).
No, IMO. Mathematically it doesn't really make sense and talking abo

Hi
Tim Düsterhus and I have created an RFC to add new methods that solve
commonly encountered use cases to \Random\Randomizer. Specifically
creating a random string consisting of specific bytes and generating
random floating point values.
