how does Roblox Round the Numbers off?
all I can think of is maybe, Convert it into a String and then find the '.' and Numbers after it, then for .floor just takes out the '.' and the Numbers after, for .ceil it would remove the '.' and all the Numbers after it as well, but would do +1 to the Number that they got...

I'm pretty sure those functions are implemented in native Lua, not just Roblox. If that is the case, then go read Lua's source code. |

It's probably something super complicated. Don't worry about it. |

ah well I done it my way XD
u'll be able to check it out soon! XD

In my experience .floor is a lot more accurate than .ceil |

Both are equal in regards to accuracy. Different tasks call for different operations. |

It's not complicated at all, in fact there are many ways to actually do it. |

cnt, be my guest, tell me...
1 comes to mind, Divide...
check maybe wat the Numbers after the '.' are and then somehow find a Number that would Neutralize those XD

local floor = num - (num % 1);
num % 1 returns the fractal part (anything after the decimal point) so I just remove it from the main number.
That's probably the easiest way in Lua without using math.floor (the easiest way i can think of right now, at least) |

function round(num)
num = tostring(num)
local decpattern = "%p%d+$"
local numpattern = "%d+"
local dec = num:match(numpattern)
local num = num:match(numpattern)
dec = tonumber(dec)
num = tonumber(num)
if dec < .5 then
num = num + 1
else
num = num
end
return num
end
print(round(2.85))
-> 3 |

damnit! XD
am so Stupid! XD
I used String.Manipulation for my math.floor XDDD
Convert to String, then back to, Number XD

No, you really don't want to convert your number into a string then back.
It's better to do number stuff on numbers |
|
|
well i don't know how to do it with math :l |

You probably learned it in elementary school.
Ever done something like this:
5 / 3 = 1 remainder 2 |
|
|
yeah but then we had to do decimals.. which sucks ass.
so what exactly does % do? its been so long since i did that and i think i forgot. |

It returns the remainder, that's all :) |

i forgot how to do remainders though.. ugh |
