 - `java.debug.settings.showLogicalStructure`: show the logical structure for the Collection and Map classes in "Variables" viewlet, defaults to `true`.
 - `java.debug.settings.showToString`: show 'toString()' value for all classes that override 'toString' method in "Variables" viewlet, defaults to `true`.
 - `java.debug.settings.maxStringLength`: the maximum length of string displayed in "Variables" or "Debug Console" viewlet, the string longer than this length will be trimmed, defaults to `0` which means no trim is performed.
+- `java.debug.settings.numericPrecision`: the precision when formatting doubles in "Variables" or "Debug Console" viewlet.
 - `java.debug.settings.hotCodeReplace`: Reload the changed Java classes during debugging, defaults to `manual`. Make sure `java.autobuild.enabled` is not disabled for [VSCode Java](https://github.com/redhat-developer/vscode-java). See the [wiki page](https://github.com/Microsoft/vscode-java-debug/wiki/Hot-Code-Replace) for more information about usages and limitations.
