digitalmars.D.learn - Random.next is deprecated

Hi,

In Tango I want to use Random.next(uint i) to generate a random number
between(0,i) but the compiler told me the next(...) function is deprecated.So
what is the equivalent function?
Thanks,
Sam

import tango.math.random.Kiss;

Kiss.shared.toInt(i)

Dumb name, but it's pretty much the same thing :)

Dunno.  Maybe they're planning on having other kinds of RNGs in
tango.math.random.

I was wondering about that Kiss module too.  I really hope it's not
Kiss as in "keep it simple stupid".  If so I think I'm going to barf.
Please tell me there's some RNG algorithm known as Kiss.  Googling
didn't turn it up, but maybe my google-fu is just weak.

It's the name of a RNG by Marsaglia.
287 	+ a simple RNG

Whew!  I was afraid Tango had gone all cutesy on us for a while there.
Like out with tango.group, in with Tango "Kiss" modules.
Seriously.  So glad to hear it's just the name of a RNG.  Sorry to
find out my Google-fu is so weak, though.  :-(

Get your vomit bag ready.  Yes, Marsaglia came up with it and named
it, and yes, he named it after "Keep it simple stupid".  :P

I figured that was probably the case.  But for some reason that
doesn't bother me.
I guess I don't really expect mathematicians to have any aesthetic sense.  :-)
I was just afraid Tango was going to start having "Kiss" modules pop
up in every package.
