CAS, negative numbers, and ROUND - Helge Gabert - 09-14-2015 02:07 AM [attachment=2533] This doesn't look right, when compared to ROUND() in Home. Firmware 8151. RE: CAS, negative numbers, and ROUND - roadrunner - 09-14-2015 12:06 PM Xcas does the same thing: [attachment=2534] I have no point or conclusion, however, just Xcas does the same thing. -road RE: CAS, negative numbers, and ROUND - Helge Gabert - 09-14-2015 04:53 PM Seems like one has to add 1 in order to get the correct result (assuming rounding to 0 significant digits is desired). Take -0.2: ROUND(-0.2) should result in -0.2. ROUND(-0.2,0) should result in 0. ROUND(-0.2,1) should result in -0.2 ROUND(-0.2,2) should result in -0.2 ROUND(-0.2,3) should result in -0.2 And that is what Home shows, but not CAS. |
