[Qgis-user] QGIS 3.10: Dimensioning with on-board equipment

[Richard McDonnell]

Thanks Karl,
Yes that’s correct, slight typo there. For two decimal places it would be as you have shown, so for the Meters part of the dimension adding the number of decimal places will be required, but for the Centimetre, leaving the number of places off, rounds the value to the nearest whole number, so keeping it as shown would be correct.
The corrected formula should look like below.

round( $length, 2) || ' m' || ' ( ' || round(100*( $length) ) || ' cm)'

Regards,

Richard

Hi!
Wouldn’t that be round($length,2) for getting two decimal places for meters?

Hi,
In my original response, I mentioned using round(100*( $length) ) || ' cm' which would give you the dimensions in centimetres only.
If you want meters only then remove the 100*, which would look like this round($length) || ' m'

Now if you want both dimensions shown, for example <-- 10.52m (1052cm) -->, then this can be achieved by using the following

round( $length) || ' m' || ' ( ' || round(100*( $length) ) || ' cm)'

Hope that helps!!
Regards,

Richard

Hi Richard,

As I had written to you on April 20, I have successfully implemented your proposal.

The only thing missing is an answer to my question:
How would I have to change the command to get a result in m.(,)cm (e.g. 10.52 m or 10,52 m) format?

Regards,

Hartmut
