HP-Prime: After so much whining...

[jte]

One aspect of the calculator that hasn't been discussed much here is that it is the first calculator (to my knowledge) that, as shipped from the factory, makes any attempt to bound numerical round-off across general sequences of floating-point operations. While this ability is currently limited to the Advanced Graphing application, if it were polished up (got its is dotted and ts crossed) and further exposed to the user, this ability would, when applicable, clearly be a fundamental improvement over previous calculators (again, to my knowledge & as shipped from the factory).

(Reliable bounds on numerical error convert computed results from stating that "this is what the floating-point algorithms produced" to "the exact infinite-precision real arithmetic result lies between … and …")
