Section 5.1.2.10 of JT 9.5 (ISO 14306 of Dec 2012) declares the 4x4 elements of the transformation matrix to be of the F32 (single precision) data type. This is the same as in JT 8.1, revision D, section 7.2.1.1.2.10.
However, I've got a JT 9.5 file where these are definitely stored as F64. Is this a typo in the standard or an error in the software that produced the file?
