Simple question, how can I remove certain digits from a number?
Ok, so I made a script that generates smooth Roblox terrain, but it requires a random seed and I don't want to have the same map twice. So I'm getting my seed by
local diffnum = (tick()*10000)
local Seed = math.randomseed(diffnum)
This works, but the seed is so large that there is barely a difference between seeds.
Example =
->15622355456157
->15622355736583
What I want to do is remove the first 7 digits of the number so I get
->5456157
->5736583
Any help with this? Thanks.

You can use some string manipulation and do something like tonumber(string.sub(tostring(diffnum),7)), which will get get the 7th character and on of diffnum and convert that returned string to a number again. Hopefully someone may produce a more extensive answer from this comment. M39a9am3R 3210 — 5y

local Number = 23123213 --example local StringNumber = tostring(Number) --Makes the number a string so we can do :sub on it local NeededOne = StringNumber:sub(StartingDigitWanted, EndingDigitWanted) --the numbers you want until it meets the digits you don't want local NeededTwo = StringNumber:sub(StartingDigitWanted, EndingDigitWanted) --the numbers you want after the digit(s) is found local FinalString = NeededOne .. NeededTwo --Puts the digits back together local FinalNumber = tonumber(FinalString) --Makes the string back into a number
