This actually is quite surprising. If you play around, you quickly discover the epsilon does not correspond to any standard mantissa sizes. In fact, Google appear to represent numbers to a precision of 1 part in 333333333333333: https://www.google.co.uk/search?q=333333333333334+-+333333333333333 https://www.google.co.uk/search?q=333333333333334+-+33333333... and all smaller positive successive integer pairs yield 1 https://www.google.co.uk/search?q=333333333333335+-+333333333333334 https://www.google.co.uk/search?q=333333333333335+-+33333333... and all larger positive successive integer pairs yield 0 what the hell kind of numeric representation does that?
