Hello!

I was wondering why when I enter a value (let's say 3.2) in a parameter, it automatically changes it to 3.2000000000000002.
If I enter 3.0, it works. But as soon as add a number after the “dot” it adds .0000000000000002.
My OCD cannot handle it.

Right now, it's doing it with on a box sizeY.

Is it a bug? Thanks

It's not added, that's just the closest number to the value that exists. There's no such number as 3.2 in floating point. Floating point can't represent all decimal numbers exactly.

Just left click on the word “Size” and it will toggle back to normal human numbers.
