Controlling precision of generated floats in svg

I'm building a gastby plugin to integrate plantuml with their remark/mdx generation.

See https://github.com/baerrach/gatsby-remark-plantuml

Everything works fine.

My test cases are storing the generated svg's to do textual diffs against to check for bugs.

On two different windows machines using the same version of Java:

$ java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)

will produces different results.

Here is just one example:

    - <g id=\"graph0\" class=\"graph\" transform=\"scale(1 1) rotate(0) translate(4 226.9)\">
    + <g id=\"graph0\" class=\"graph\" transform=\"scale(1 1) rotate(0) translate(4 226.895)\">


You can see the precision in the translate, in the original file was "226.9" and in the newly generated file "226.895"

I've downloaded the code and had a quick look but its too much for me to locate how the output is generated.

I can see no option available to limit the output precision so that I would have more chances of getting stable output for diff comparison.

Is this something that I can force plantuml to do?
