Expected behavior and actual behavior.

I expected to be able to store more than 4 decimal places to the M values of vertexes. Instead when I store 7 decimals I get rounded values after I write my features to the layer.

Steps to reproduce the problem.

Create a new feature in memory and assign a geometry object that contains points with M values. If those M values have more than 4 decimal places they will be rounded after the feature is added to the FileGdb layer.

Operating system

Windows 10

GDAL version and provenance

I've tested both 2.4.3 and 3.4.3 and the behavior seems to be the same. I'm using the swig C# libraries and adding the Esri FileGdb plugin to my environment.
