How do we input the r on multiple circles all at once?

Many times an exported LibreCAD .svg has circles that are .00001 so how can we do a correction all at once?

And;

I noticed we can put longer radii measurements into the svg. How can we change the length of the lines to a longer measurement?

It's incredible what extra data the svg format can hold. Then I noticed the longer r does not remain when the circle is moved. Although I want it to remain. Is there a way yet to do that?

Thank you kindly.

I´d use Object->Transform->Scale: "Apply to each object separately" 

Object >Transform >Scale, Apply to each object separately;

Upon selecting more than one circle, the Height & Width make rectangles so then the circles become oblong.

Alas, the mm in scale only goes to three decimals; I wanted longer than five decimals. To adjust the numbers in the radii of a bunch of circles with a single click.

If you change Edit>Preferences>Input/Ouput>Numbers>Numberic Precision to 15 for example.

It should leave the 'r' value unaffected when the circle is moved.

I don´t see any reason why this shouldn´t work from my testing before I replied. 

Edit>Preferences>Input/Output> numbers? @inklinea
 

Input/Output

[Y] Use current directory for "Save As..."

[N] Add label comments to printing output

[N] Add default metadata to new documents 

The tutorial did not expound upon the Inkscape Preferences Dialog in Inkscape: Guide to a Vector Drawing Program.

Never-mind @inklinea, Numeric Precision was found in Preferences > SVG output.
