Hi gens,

I faced this situation a few times. Sometimes if I get some length from the drawing and then try to work with it in lisp some functions do not return proper values.

For example Length of a segment is 12.5 (taken from the drawing), when I compare it to a real number

(<= 12.5 SEGMENTLENGTH) might return nil.

Well as far as I know 12.5 is equal to 12.5

, so I assume the issue has to do with precision.

Maybe in reality it considers for example 12.5000001, but the Watch Window will only show that SEGMENTLENGTH is 12.5.

Questions:

1. How can I see in the Watch Window the exact value instead of 12.5 in this case?

2. Is the only solution rounding the variable before I compare it?

Thanks
