Summary	0003808: "2nd length" in "Pocket parameters" shows wrong value when a negative f(x) was defined
Description	When you input a negative f(x) value in "2nd length" (i.e. -20.0) then 0.0 will be shown in the dialog after closing the f(x) input and reopening the "Pocket parameters". See at the attached picture: ) "2nd length / f(x)" = -20.0 ) shown value = 0.00 mm All was tested on FreeCAD_0.18.15711.
Steps To Reproduce	1.) Add a new cube (100x100x100) in "Part design. (look at "Pad") 2.) Create a Pocket on this cube. 3.) Select "Two dimensions" in the "Pocket parameters" 4.) Input 120mm at "Length" 5.) Press f(x) in the "2nd length" field. 6.) Input -20 7.) Press OK in the f(x) input 8.) Press OK on the "Pocket parameters" 9.) Double click on the new pocket in the "Combo view / Model" 10.) Now you see "0.00 mm" instead of "-20.0 mm" in the "2nd length" field. Perhaps it will be a good idea to allow to input a negative value directly in the "2nd length" field.

chrisb 2019-02-01 12:58 developer ~0012574	The behaviour of negative 2nd length is not documented for negative values, and it is not possible to enter them as non-expression values. So any behaviour is acceptable and it is definitely not a bug. Nevertheless, the behaviour is very interesting by defining a positive offset of the pocket. So it can well be a feature request. This should be discussed in the forum. @markus51, please add a forum topic (which in fact you should have done anyway before creating a ticket).

markus51 2019-02-01 13:34 reporter ~0012575	"...is definitely not a bug...." is's an interested opinion. We can discuss whether negative values are allowed, but if the formular (f(x)) calculates an negative value ist MUST be shown in text field ! How a user should see that his formula produces negative value, wenn in the text field always showes "0.00", that's nonsens ? Nobody finds such an error.
