it's simply
Percent = (k/max); basically. both k and max are floats

Oh, I actually didn't know that.

my bad

#

but seriously, if you are adding +1 to a float that's at the end of its significant digit accuracy it will floor

#

public class FloatExample : MonoBehaviour
{
    const float max = 25000000;
    [Range(0,max)]
    public float k;

    [Range(0,100)]
    public float percentage;

    private void OnValidate()
    {
        percentage = (k / max) * 100;
    }
}

which is why you can represent larger numbers, but the accuracy diminishes

so would what Praetor was talking about solve my issue in this case? making percent, max, and k all doubles instead of floats?

#

in your case 'k' represents an index, so that should stay as an integer

brittle thistle Jan 12, 2022, 4:45 AM

#

but won't dividing an integer by a double result in the same issue as dividing an int by an int?

#

or is that not a problem

It will fix the "67%" problem. I don't know if it will solve your actual issue because I still actually don't understand what you're doing

#

I can't think of any good reason to iterate over every single unit coordinate
