Why sometimes i cannot force certain value in editor to be zero ?

Like Pos Y, it keeps at "-3.051758e-05" instead of "0", i know that value is very very close to zero, but i everytime i sees something not default i always attempt to fix it, it just wont allows me. Are there anyway to allow me to force unity editor to be like 2-3 decimals ?

 

It's a bug of some sort, I'm sure. For all intents and purposes, that value is zero. But if you, like me, have something inside you that requires the field to actually read zero, what you can do to work around it is first change the field to a non-zero value (i.e., "5"), then change it to zero.

It's a bit annoying to have to do this when you're copying a bunch of UI elements and have to change/reset half the values, but it works.

 

Right, I assume what's going on is when you enter a value, Unity compares it to the previous value to see if it's changed. If it hasn't changed, it doesn't reapply your entry, because in some cases that could have unwanted side-effects.

But in a case like this, it's comparing floating point values, and checking for equality on those is a very dicey proposition. So it checks for "close enough" equality. And a number like that is close enough to 0 that it doesn't reckon you've really entered a new value.

 

oh it worked, didnt know changing the value to other value 1st then back to 0 will make it work, really helps alot, thanks.

 

Or as Brackeys put it "It's as close to zero as you can get". I remember seeing them mention it in one of their tutorials back when the Unity UI was still very new. It's definitely a bug.
