So far only the HP Prime in Home mode had lessaccurate answers. It appears that the Casio's I tried have a resolution of 15significant digits. The TI's have either 13 or 14 digits. The HP Prime has 12 digits, the same as the Saturn based HPs. I also found it interesting that the HP48/49/50 series did not have the option to calculate quadratic regression builtin to their feature set. TI graphing models have had this ability since the TI82 introduced in 1993.
