I'm not sure what you are referring to. I don't see anything in
the surround_3_12.1 that this comment could apply to.

Where floating point will be necessary is in computing the
strategic effect when a surround escape move reason is found,
but that is not very  different from what we already do with the
strategic attack/defend move reasons.
