so im making this game about planet clickers and i got this glitch were scratch if you 1.1x 3 it makes it 3.3000003 which makes my cool funky numbers not work now please if you can i need help to either somehow find a way to go around this or to make it so my cool funky numbers dont actually bug out on this weird thing

You can round it to the nearest tenths place by using this code:

((round ((value) * (10))) * (0.1))

ah i got it ty but now it does it with 7s and makes it 7.000000001 instead

Our old friend the floating point error. TUB's solution really should address the 7 version as well.

Imagine I asked you to write 1/3 as a decimal fraction exactly and without using the trick of marking it as a repeating value. You just can't do it since it is 0.333 continuing for ever.

Now computers don't use decimal, they use binary, and even storing some values we find easy like 1/10 = 0.1 a computer can't easily represent so it has to approximate depending how many bytes it uses to store the value. So you get results like you're seeing and it is up to you to round these if they don't appear the way you want.
