    Came across this link today: http://floating-point-gui.de/

    It breaks down the problems with floating points arithmetic in a nice manner. A bit easier to digest than many of the other articles on the subject.

      It would have been better to choose a shorter length than an inch for the default unit in SketchUp. It should probably be a millimeter at the largest.

        Shortest unit in SU is a 1/1000 of an inch.

          but no matter what SU still uses 1 inch as its internal unit. It converts from an inch into everything else.

            I've read that international domestic architecture is done entirely in millimeters. No fractions required.

              The UK building industry uses mm for lengths and square-metres for areas [although land-surveyor's use metres and letting-agents/developers still think in square-feet to confuse us!], day-to-day younger people use cm/m, but "oldies" [like me!] think in feet and inches: although personally I'm pretty 'bilingual' [bimetrical?] - I'll say to some one we want a rafter "50x100, 10feet long" !!!

                How about: multi-metrological ?

                I'm not here much anymore.

                  Don't get me started by mixing Latin and Greek roots ! 😉
                  I know 'multimetric' is an actual word but...
                  'Malametric' would be a purer word - using two Greek roots - or perhaps we could invent panmetric or panmetronic based on the 'parametric' model ? Unfortunately 'polymetric' is already taken in music =to do with 'more than one meter' and 'polimetry' =to do with studying politics; but something along the 'polyglot' or polymath' lines seems more attractive - perhaps polymetronic ? 😉 🤓

                    Polymetronic seems like it would require batteries. 😆

                    I take the slow, deliberate approach in my aimless wandering.
