It struck me that we could save many gigabytes of disc, and probably quite a lot of I-O, if the basic data storage type was float rather than double. We had absolutely no use for either the extra precision nor the extra range of double. I emailed Tobi Oetiker saying so and he replied that no-one had ever thought of that. AFAIK, there's still no way round using double.
