rec area doesn't show up with exact numbers calculated.

 

aaa.jpgi

when an area is created by joining 4 lines, it doesn't show up with exact numbers that is calculated by an arithmetic expression.

 

I made a rectangular using commands (line->offset->rectang).

Then I extpect to get an exat area,but it always show me the wrong area.

Even it happens when the program begins newly.

It's very small numbers,but it is annoying me. T.T

Google  for floating point arithmetic on computers.  you'll find some explanations as to how and why this happens (and it has to happen)
