Calculation of your money flow excel spreadsheet converts these cells will need to somewhere.Excel looks at the rest of a formula and then apparently starts out using trial numbers and then moves toward a result that's in the ballpark of what the equation is trying to do. Numbers extension are created by Apple's 'Numbers' application which forms part of Apple's iWork office suite, a set of applications which run on the Mac OS X and iOS operating systems, and also includes Keynote (for presentations) and Pages (for word processing).Select the PDF you want to convert to the XLSX file format. I just know it works.File extension.numbers: Category: Document File: Description: Files with a. I'm not a programmer, so I don't really know how they set up iterations. Choose your required format from the drop-down list under Excel format.That's an interesting concept.I'm just not qualified to do that. I depend on that feature for important stuff, so I'd rather stay with Excel than try to manufacture something. Sometimes Excel is stumped and I have to figure out a different approach.
Numbers Convert Cell To Calculation How To Use ItI don't know how to use it and I don't have the time to learn it. To me, that meant sorry, chump, your work is dead and you'll have to use Visual Basic instead. Then they eliminated the feature and told us to use Visual Basic. It was a major investment in time. Several years ago, I spent a lot of time putting together macros that made my work much easier. MS keeps messing around with Excel to the point I don't trust them when they announce a new version.Normally, spreadsheets insist that the dependencies between cells form a DAG (Directed Acyclic Graph), where "acyclic" is another way to say "no circular references".But I can see that it would be useful for iterative techniques. And Print Paging Subtotals Convert Between Cells Content and Comments.That's an interesting use of circular references. For example, to convert a set of dates in place to one week later, do this: add the number 7 to any cell in the worksheet, then copy it to the clipboard.The below formula can help you format number as mac address by adding a colon. Best regards.But if you only need a simple calculation, Paste Special is much simpler and faster, because you can change the value directly without any extra formulas. Also, thanks again for the info regarding disk permissions. (end of rant) Thanks for your interest.![]() You could do that by making the output and input the same cell, but for the sake of discussion let's suppose they're different cells.I've seen other spreadsheets (all obsolete, unfortunately) that would iterate for you, but they did it as a special operation, not in response to circular references. So far, no cycles.You introduce a cycle by, in effect, copying the output back to the input. The spreadsheet grinds away to produce, in an "output" cell, a hopefully better guess. The main one is the sheer magnitude of trying to do it. It's highly proprietary pertaining to very complex chemical reactions, but there are practical reasons why I also can't set up Numbers in the ways that have been suggested. Then repeatedly run the AppleScript (probably from the Script menu) to watch it converge.But there are some problems that can't be solved without a circular reference.Can you provide an example? I'd tend to think that in all cases a little algebra could be used to move all the cell's terms to be alone on the left of the "="Actually, I can't provide it. Choose standard names for the cells so that you'd only need to write one AppleScript for any number of spreadsheets. Write an AppleScript to copy the value from the output cell back to the input cell. I also set "Maximum change" to 0.001 (meaning that, if the iteration change gets smaller than that, the calculation stops. That single formula involves 5 multiplications, two additions, two subtractions, and one division.Second, Excel usually goes through several hundred or sometimes several thousand iterations before finding the "answer." In Excel 2008/Mac, you go to "Preferences: Calculation" and set the "maximum iterations". Here's an example of what I deal with routinely:First, in one example, I have a formula that involves one circular reference and reference to nine other cells many of which refer further to other cells. Before I started this thread, I had spent quite a bit of time snooping around Numbers and its User Guide, but I couldn't find anything on the kind of calculations mentioned here, so I thought I'd better call in the heavy artillery in this forum just in case I'd missed something. It handles them all.Unless Numbers is expanded to possess the functionality and capacity of Excel, I'm afraid I'm stuck with Excel. The labeling in this calculation function doesn't distinguish between circular references and unknown values where circular references are not involved. MS Excel is very good at this and does it through iteration until a solution is reached. Thanks for the input.I tried to get Apple's Numbers app to solve circular references, but all I got was a warning: "This formula can't reference its own cell or depend on another formula that references this cell." Normally, this is good advice, but there are some problems that can't be solved without a circular reference. You folks are smart, knowledgable, and very experienced. BTW, I really enjoy this forum. I appreciate the suggestions very much, but I think I need to stay where I am until Numbers is brought up to Excel's capacity. Since I don't consider myself qualified to produce a do it yourself solution, it seems my only real option is to stick with Excel. Eclipse cdt for cc for macI'm frankly a bit surprised that Excel can do it. It would never occur to me to actually use a circular reference intentionally in a spreadsheet.I do not believe there is any way to do what you're describing in Numbers. In my work, this feature is exceedingly valuable.Wow, that's interesting. Sometimes, a solution cannot be reached within the specified number of iterations, but most of the time, the problem is solved. To do that, copy the formula from your "answer" cell into some new cell (which I'll call the "next guess" cell) and remove the formula from the "answer" cell. It repeats until the value converges, if it does.Break the cycle. The newly computed value is the next guess. It plugs a number (possibly zero) into some cell in the cycle, and then computes everything (including that cell) based on that assumption. To recap:Break the cycle by splitting one cell into two: create a new cell (the "output" cell) into which you copy the formula from the original cell. Count the iterations (or look at the elapsed wall clock time) and abort if convergence is taking too long.Just for the benefit of anyone else finding this thread, here's the AppleScript that incorporates my suggestions. Otherwise it copies the "next guess" value into the "answer" cell, which triggers Numbers to iterate one more time. If they're close enough, it quits. On each iteration, it compares the values in the "answer" and "next guess" cells. Convergence means the value in the "next guess" cell, as calculated by all the formulas in your spreadsheet, matches the value in the "answer" cell.I showed you an AppleScript that would iterate once, but it could be easily expanded to iterate 10,000 times if that's what you want. ![]() ![]()
