Floating point precision error?

[min16]

Hi, I just started using Altium 18.0 and facing a weird bug. Not sure if this is my fault or some setting has gone wrong.

The bug is Altium is keep saying I'm violating a component clearance even I'm not. If you look at clearance_error.png you can see "Component Clearance Constraint (0.1mm < 0.1mm)". Many components in the same PCB file is reporting the same bug but there is one case which is not having the error (clearance_no_error.png). I also attached my clearance constraint.

Any idea why this is happening? Thanks.

Could you leave the placement as you have it now and try to set the rule to 0.09? I am just curious if that would help to remove the violation.

Hi Robert,

Yes it removes the error. But would it be a good idea to keep it that way?

Based on the message "Component Clearance Constraint (0.1mm < 0.1mm)" .... I do not know, looks like a bug (?) Clearly, that statement is not true. I would probably just set the rule to 0.099 and would not spent much more time with that.
