How do I generate a random integer from 1-5?

[Laudie3a]

 If I use random how do I convert it to an integer?

[Guruthilak]

check out the conversion palette under "Numeric->conversion"

For a Random Interger from 1 to 5 you do something like this:

Edit: I just realised, that the chances for every Number are not the same, so my version is kind of unusable for statistically correct purposes.

Its too early in the morning 😉

Edit2: Also I realise further, that my version won't output 1-5 but 0-5 so it is not even what you wanted. D**n what did I do 😄

Cheers

Could you just use a +1 increment after the multiplication? What does the I32 do exactly?

"To I32" converts your floating point number to an integer, as you specified in your first post as requirement. 😉

Here' a version that gives all 5 numbers with equal probability. Instead of explicitely converting to I32, I use the output configuration of the +1. Same difference. 😉

dear altenbach,

just some "additional" inputs to make it configurable... please kindly comment and advise. Thanks!

Wouldn't you have to multiply times 4 vs 5. If the random number give you a one then you would get 5 and add 1 to it giving you 6.

No aestet, Altenbachs solution is perfectly fine.

The dice generate a Number between 0 and 1 (Not including 1!!) Multiplied by 5 that is a Number between 0 and 4.999999.

The next triangle always rounds the Number down, so that you can only get 0,1,2,3 and 4 everything with equal propablity.

Plus one you get 1,2,3,4 and 5.
