Rand(Min,Max)??

[Ian Price]

I know that GLBasic supports random numbers in the form of RND(Max), but this always returns a value between 0 and the Max value.

Is there a command like RAND(Min, Max), where the command returns a value between (and inclusive of) the two values?

I have only skimmed through the Index, so maybe I missed a similar command. Does it exist, and if not, can it be added?

[EDIT] BTW I created a function to do this, but a built in command could be useful to newcomers.

The normal behaviour of basic is to give a number between 0 and 0.9999. This one you multiply with whatever you want the range to be and then add the number you want to be the start of the range. If you want newcomers to have it easier, post your function for them to use too! That's what it's all about anyway, isn't it?

Hm... I though this RND would be theeasy to use:
For RND(5,7) I use:
5+RND(7-5)

Hmm Gernot i think RND(0,9) for example, could be better then RND(9).
So you can do RND(5,10),  5 MIN 10 MAX....
Should be easier to use...

@ iprice

you can use that:

negativ and positiv values!

ex.: RAND(-10,10) or RAND(10,20) or something like

Code (glbasic) Select Expand

FUNCTION RAND: minimum, maximum

RETURN minimum + RND(-minimum + maximum)

ENDFUNCTION

That's very similar to the function I came up with

Why is it every new Basic dialect has to come up with it's own way of using RND? Why not stay with the 0 - 0.9999 and leave the programmer to use it as he sees fit? If you want negative values you just do RND() * 20 - 10 and you have a range between -10 and +10.

Sorry, but I prefer the GLBasic way!
It's very comfortable ;-)
