I think he describes a procedure which guarantees that the last digit of the representation is exact. So that we (in decimal) can have 3.14 as a representation for pi, but never 3.13 or 3.15. But this is hardly 'solving floating point errors' and hardly novel.

The whole technique smells a bit fishy to me, but it might be genuine (in any way, the article seems more like marketing since the technical merit is not immediately obvious, and the difference with existing techniques not immediately clear).
