Thank you so much for letting me know about this. Is there any way to round the numbers up to the tenth place? if not thats fine. just wondering for sake of the exact pitch

Using math.round and multiplying the number by 10 (to make it an integer since math.round only works with integers) and dividing it by 10 (to make it a decimal again)

local R = Random.new():NextNumber(0.8, 2)
FireSound.Pitch = math.round(R*10)/10

The amount of 0 will be the number of decimal places: 10 = 0.1, 100 = 0.01, etc.
