[Implemented] Random

[Polo]

I've made the request before, but could the function Random have two parameters ? I just don't see why values should specificaly start from 0, we need the ability to choose the start value

[Fred]

What about this: Random(10)+StartValue.

May be it should be written in the doc

[Joakim Christiansen]

Code: Select all

Random(15)+5

It will now start at 5 and end at 20...

Why don't you want to add it?

[Fred]

It's just useless.

[Polo]

Far from useless.
It makes the command a little bit more advanced without too much work...
It's good to have workaround, but too much workaround kill easy programmation

[nco2k]

hmm... i agree. it would be nice to have this one. cause its not hard to implement that "brand new feature". its only a matter of few seconds(?!) i guess.

Code: Select all

Procedure MyRandom(Min.l, Max.l)
  Result.l=Random(Max-Min)+Min
  ProcedureReturn Result
EndProcedure

MessageRequester("your lucky number is... ;)", Str(MyRandom(10, 20)))

p.s.: there is almost always a workaround, for almost everything, but still...

Currently the command take 1 argument, which is max. So adding min as optional sounds wierd..

[Joakim Christiansen]

I also want things to be easy, but I agree with Fred on this.
The random function is like this in every language(i think), why should it be different in PB.
Min-Max on random sounds quite stupid... (my personal feeling)

[blueznl]

pretty numb, but what the heck...

Code: Select all

Procedure.l x_random(low.l,high.l)                                  ; generates a random int in the range low to high
  ;
  ; *** return a random var from and including 'low.l' to and including 'high.l'
  ;
  ; (i find the pb random function somewhat confusing now and again...)
  ;
  ProcedureReturn low+Random(high-low)
EndProcedure

Yea most randoms only return a float/double from 0 to 0.99999...

So you'd need to do rand()*10 to get an integer from 0 to 9 and add whatever constant you need for max/min, etc. Already easy enough. No change is my vote.

[blueznl]

it works, i'd rather add a rnd() for floats to emulate other languages than change the current one

Here is what I want
And also, nobody is speaking of optional parameter

No, there are language where the Minimum parameter exists. And I agree with others, it would be useful.
If I remember well, in PHP and MIrc there is the parameter LowValue. I don't know for C, C++ etc.

> nobody is speaking of optional parameter

It's not needed. Some things just need to be done by the programmer.
