Lua Simple question about math.random

[Deleted member 141899]

Hello, what a % of chance is it?

if math.random(1000) > 50 then

i don't understand.

Thanks.

math.random returns a random number between 0.00000000000001 and 1 when no argument is used or 1 and the max value passed to math.random (max value you can pass is 999999999999999999).

However although math.random will return a decimal number when no argument is passed to math.random, you may only pass math.random an argument which is a whole number (e.g. 1, 2, 3 etc) otherwise you will generate an error.

You can also pass 2 arguments to math.random

-- math.random(min, max)
math.random(10, 20)

You can test your condition on this site

Just copy the code into the box and hit run

x = math.random(1000)
print(x > 50, x)

Basically, that will generate a number between 1 and 1000 and check if that number is higher than 50.

(50 / 1000 ) * 100 = ( 5/100 ) * 100 = 5

It's 5%.
