Question - Is there any way to randomly pull a variable from an array?

[Ionis]

Screwing around with the Bazaar.mac and I've done very little in regards to programming using macro language but I've got a fair amount of experience with programming in general. I was wondering, if I declare an array (which hopefully I did right) is there any way to randomly choose a value from that array?

For example, say I wanted my determinant percentage that calculates my items price to be chosen from 3 different values:

[CODE lang="ini" title="Array"] /declare pricePercentage[3] float outer
/varset pricePercentage[1] 0.92
/varset pricePercentage[2] 0.95
/varset pricePercentage[3] 0.97[/CODE]
Would be my arrays declaration (I think), how would I randomly choose a value to throw in to the equation calculating the items price, something like a misc.random?

Or is there a better way to do this?

Thanks!

/declare randomInt int outer 0

could be created as an outer variable.

and according to mq2 wiki for math TLO.

https://redguides.com/docs/projects/macroquest/reference/top-level-objects/tlo-math/

  /echo ${Math.Rand[500]}

Echoes a random number between 1 and 500

So then we can then

/varset randomInt ${Math.Rand[3].Int}
/echo ${pricePercentage[${randomInt}]} is the value stored at ${randomInt}

Hope this helps.

It looks like Math.Rand uses 0 which ends up being null. I'll toy around with it, but anyone know any way to fix this? Pic for reference, works great otherwise!

Edit:
Whipped up a simple fix:
[CODE lang="ini" title="Null fix"]
/varset percentagePicker ${Math.Rand[3]}
/if (${percentagePicker}<1) {
/varcalc percentagePicker ${percentagePicker}+1
/echo Null avoided!
}[/CODE]
Threw this before the varcalc on the percentage. Essentially just sets the variable, checks if it's 0 and if it is sets it to 1 then does the varcalc and now it's working like a charm! Thanks again!

Edit 2:
Realized Math.Rand can take a min argument so I kept the exception catcher in there just in case but instead used:
[CODE lang="ini" title="Math.Rand"]/varset percentagePicker ${Math.Rand[1,5]}[/CODE]
so 1 is the minimum and 5 is the maximum (increased array size to 5)

Hopefully last edit! Thanks again!
