RobDraw Posted May 10, 2016 Share Posted May 10, 2016 Ummm... One of AutoCAD's finest points is in how accurate it can be as long as the user is willing to take the necessary steps. In this case we are looking at rounding off. The table is probably set to do that. Quote Link to comment Share on other sites More sharing options...
chrisdarmanin Posted May 10, 2016 Author Share Posted May 10, 2016 you mean i can remove it?? but doesnt make sense to me. the formula is basically (b3*c3)/1000 up to row 7 then sum of column d. how can autocad mess that up?! Quote Link to comment Share on other sites More sharing options...
RobDraw Posted May 10, 2016 Share Posted May 10, 2016 It's NOT messing it up. What you are seeing is more accurate than if it were showing nines instead of zeros. It is rounding it off because it can't display all of the decimal places. I see well over a dozen decimal places in the properties, but only six in the table. What do you want it to do with all the other nines? Forget they are there? Quote Link to comment Share on other sites More sharing options...
danellis Posted May 10, 2016 Share Posted May 10, 2016 I think is question is the opposite - he doesn't know where all the nines are coming from. And I can see his point - there's a series of numbers that appear to be entered manually which are all integers. These are then multiplied by 0.26 and totalled. No, I don't see how a discrepancy of 0.000000000001 has appeared. dJE Quote Link to comment Share on other sites More sharing options...
RobDraw Posted May 10, 2016 Share Posted May 10, 2016 Okay, I was thinking about it backwards. Coffee hadn't kicked in yet. If the formula is basically (b3*c3/1000), is there more to it? What is it exactly? Quote Link to comment Share on other sites More sharing options...

BWA HA HA HA HA! However, to be helpful. Hit the F1 key and use this ribbon in AutoCad displayed below Quote Link to comment Share on other sites More sharing options...
SEANT Posted May 10, 2016 Share Posted May 10, 2016 That is a quirk of the Decimal Binary Decimal conversion. Thin of it as similar to 1/3 = 0.3333. If 3 * 1/3 = 1, but 3 * 0.3333 = 0.9999, what happened? That is a quirk of all computing operations, be it Calculator, Excel, AutoCAD or anything else. It really depends on where a program wants to initiate the rounding operation. Quote Link to comment Share on other sites More sharing options...
TheCADnoob Posted May 10, 2016 Share Posted May 10, 2016 WHYYYYY!!!!!!!!!!!!!! seems a pocket calculator is better than autocad A pocket calculator doesn't know about concepts like significant digits. The calculator allows one to make that mistake all by there self where CAD apparently tries to stop one from doing it. your input precision doesnt go past the 100ths so cad cuts it off there. If you want to see the trailing '9's make sure LUPREC is set as high as it can go and manually trim off the last couple 9 until you hit the LUPREC number.
