And I couldn’t stop asking myself, “how can we do anything with only 0 and 1?” I wondered what were all those cables and what were their purposes. You can always ask an expert in the Excel Tech Community or get support in the Answers community.When I was a child, the back of my cathodic TV amazed me. When this formula is evaluated by pre-dynamic array Excel it will return a #NAME! error value. If you later open this formula in pre-dynamic array Excel, it will appear as =A1:A10+_xlfn.SINGLE(A1:A10) with the in the mixed formula appearing as _xlfn.SINGLE(). If you chose to reject the formula proposed by the dialog, the mixed formula will be committed. For instance, if you enter will see the following dialog: When dynamic array enabled Excel detects the creation of a "mixed formula", it will propose a variation of the formula that implicit intersection throughout. Pre-dynamic array only supported formulas that did i) implicit intersection or ii) array calculation throughout. A mixed formula is a formula that relies on both array calculation and implicit intersection, this was not supported by pre-dynamic array Excel. This occurs when you commit a mixed formula. If you author or edit a formula in dynamic array Excel that contains the operator, it may appear as _xlfn.SINGLE() in pre-dynamic array Excel. When they do, the original formula would have triggered implicit intersection. User Defined Functions can return arrays. When it does, implicit intersection would be intersection could occur. The OFFSET function can return a multi-cell range. The INDEX function can return an array or range when its second or third argument is intersection could occur. No change - No implicit intersection could intersection will occur, and Excel will return the value associated with the row the formula is intersection could occur. No change - No implicit intersection could occur, as the SUM function expects ranges or arrays. See Excel functions that return ranges or arrays for more details. A common exception is if they are wrapped in a function that accepts an array or range (e.g. SUM() or AVERAGE()). It's important to note that there is no change to the way your formula behaves - you can just see the previously invisible implicit intersection now. Common functions that could return multi-cell ranges include INDEX, OFFSET, and User Defined Functions (UDFs). Generally speaking, functions that return multi-cell ranges or arrays will be prefixed with if they were authored in an older version of Excel. If you remove an automatically added later open the workbook in an older version of Excel, it will appear as a legacy array formula (wrapped with braces ), this is done to ensure the older version will not trigger implicit intersection. If it returns a single value (the most common case), there will be no change by removing it returns a range or array, removing will cause it to spill to the neighboring cells. It depends on what the part of the formula to the right of the returns: ![]() Consider the following formula in a table Here the indicates that the formula should use implicit intersection to retrieve the value on the same row from. The symbol is already used in table references to indicate implicit intersection. ![]() ![]() Where an old formula could invisibly trigger implicit intersection, dynamic array enabled Excel shows where it would have occurred with the Why the symbol? ![]() With the advent of dynamic arrays, Excel is no longer limited to returning single values from formulas, so silent implicit intersection is no longer necessary. If the value is an array, then pick the top-left value. If the value is a range, then return the value from the cell on the same row or column as the formula. If the value is a single item, then return the item. If your formula was returning a single value, then implicit intersection did nothing (even though it was technically being done in the background). Implicit intersection logic reduces many values to a single value. Excel did this to force a formula to return a single value, since a cell could only contain a single value. It's important to note that your formulas will continue to calculate the same way they always have. As a result, you may notice appear in some formulas when opened in dynamic array Excel. Upgraded Formula LanguageĮxcel's upgraded formula language is almost identical to the old language, except that it uses the operator to indicate where implicit intersection could occur, whereas the old language did this silently. Dynamic arrays bring significant new calculation ability and functionality to Excel. The implicit intersection operator was introduced as part of substantial upgrade to Excel's formula language to support dynamic arrays.
