Sorry this is late. I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.

From the introduction, this doc defines textual conventions for the representation of floating-point numbers. The security considerations section points out that the doc only defines textual conventions, and says, "Meaningful security considerations can only be written in the MIB modules that define management objects.  Therefore, this memo has no impact on the security of the Internet." I agree with this.
