In file format spec, no.
In the Official Library spec, yes:

Note: This is only for files in the official library. While the file format is silent and the official library spec could be considered the de facto "standard" in most use cases, maximum precision is ultimately dependent on the data type that the LDraw editor in use uses to store the value listed.
