Is this a bug: random(1,1,1) returning 0

[sshrum]

This function works great until the min and max match. I'm using it like this

$iNext = random(1,$aFiles[0],1)

If there is only 1 entry, I'd assume that a random between 1 and 1 would return...well...1

Min cannot equal Max

And again,.. They never say thanks, or whatsoever.

3.2.10.0 always returns 1

3.2.11.1 always returns 0

Ok then...can we ask that a feature of the random function be that if given a range of 1,1 while requesting integers, that it return 1?

I understand that with float values random will never hit the end values whenas integer call are inclusive.

The reason I ask is that alot of us deal with arrays and sometimes the array will have 1 entry in it...granted I could code for and array of 1 but honestly...I feel a random # generator given a max and min of 1 should return one.

just my 2 cents.

Thanx

You can ask, but given the rejection of the bug report - I kinda doubt it will go thru.

Edit: I Googled a few other forums and opinions vary on allowing min to = max.

If min = max then it is impossible for the return value to be random so returning 0 and setting @error to 1 is the correct way for the function to work.

Understood...but given that there may be a situation where (when working with arrays of varying sizes) one may pass a $array[0] of 1 to random()...

It would just be nice if it would return 1.

I'm already testing for $array[0]=0 before working on the array...now I have to test for $array[0]=1 before I send it to random.

If $array[0] = 1 then

return 1

else

return random($array[0],1,1)

endif

Func Random2($min, $max)
If $min = $max Then Return $min
$result = Random($min, $max,1)
Return SetError(@ERROR,0,$result)
EndFunc

hehe weaponx...see the post above yours. I editted it just as you were posting

But thanx for the input

I actually think I'll do as weaponx described...create a new func in my personal UDF called _Random and just do like his sample shows...

I know this is beating a dead horse but honestly, I think (1,1,1) should return 1
