Fusion 360 Sketch Platform Math Incorrect

[0171352]

Hello I have been using Fusion 360 over an year now and ever since the latest update I've have been faced with an problem.

When I draw an circle of 3.898 and I put in my calculator 3.898+0.105 to give it an offset of 0.105 it equals 4.003in

Now When I draw another circle to create the offset which is the 4.003in circle inside my circle I get an offset of 0.053 when it's supposed to be 0.105.

Can anyone explain why this is happening and even when I use the offset tool in Fusion 360 from 3.898 and I use the offset tool to make 0.105 the circle it creates is 4.108.

How does 4.108-3.898 makes 0.15 when it's makes out on an calculator 0.21! 

As well all my measurements are at inches.

Apples and Oranges.

Radius and Diameters.

Half of 0.105, happens to be 0.0525 rounding to 0.053.

Yes, I understand now that it may be in radius since it's half of what I need but how would then be able to get out of radius mode or how would I be able to use it as an diameter.

Because I an using the circle tool via diameter and not specifying it to become radius.

Draw the circle without nominating a size, you can then dimension blue circles using the Radius option, with the right mouse click Menu.
