Re: [sc-users] rand question

[Joshua Parmenter <joshp@xxxxxxxxxxxxxxxx>]

See the SImpleNumber helpfile:

rand

Random number from zero up to the receiver, exclusive.

rand2

Random number from -this to +this.

rand excludes the receiver, rand2 includes it.

Hi list

I am puzzled by the difference of rand2 and rand.

I've never stumbled into this before, maybe it's my build

or I am hallucinating but 3.rand never gives me the number 3.

However, 3.rand2 gives me both -3 and 3.

A little test code:

(

a = List.new;

10000.do{

a.add(3.rand)

}

)

a.asString.contains("3")

(

a = List.new;

10000.do{

a.add(3.rand2)

}

)

a.asString.contains("3")

What's up with this?
