The pi function works the same in Excel for Mac as it does in Excel for Windows. Then find the letter “π” and double click it to insert it to the cell. In the Symbol dialog box, choose “Greek and Coptic” from the “Subset” dropdown. In the ribbon, click on the “Insert” tab, and then click “Symbol” on the far right of the menu. If you forget the ASCII code, you can always enter the Greek letter through the symbol dialog. Then release the ALT key, and the symbol, or Greek letter, “π” will be inserted in the cell. To add the pi symbol to a cell this way, hold down the ALT Key and type 227 on the number pad.

The quickest way is to use the Excel ASCII character code for pi. If you want to enter the pi symbol, or Greek letter “π”, into a cell in your worksheet, there are a couple of different ways to accomplish this: Excel Character Code for Pi However, when the variable is stored as a Double, it contains all 15 figures, the same as those returned by the worksheet function: When the variable is stored as a Single, it only contains 7 figures (as seen in the Immediate window): The precision of the value stored in the variable will be affected by whether it is a “Single” or “Double” data type. Then you can use the variable “pi” in all the subsequent lines of VBA code for that function or subroutine. Instead, create a variable called “pi” and set it equal to the results of the worksheet function. If you need the value of pi multiple times in your code, it’s going to be really irritating to type () over and over again. If you need to use the constant pi in a VBA subroutine or user-defined function, you’ll have to use the WorksheetFunction object because there is no VBA function for pi. Remember, pi is a function in Excel, and even though it doesn’t take any arguments it still needs to be entered with parentheses to be recognized as a function by Excel. If you’re trying to use pi in an Excel formula and you are getting a #NAME? error, it’s because you’ve forgotten the opening and closing parentheses. There really isn’t much that can go wrong with the pi function, except for the #NAME? error. The pi function can also be used as an alternative to the RADIANS or DEGREES functions for converting from degrees to radians or vice versa. …and approximating the period of a pendulum: …calculating the volume of a sphere from the radius:
…calculating the area of a circle from the radius: A few obvious examples are calculating the circumference of a circle from the diameter: There are many, many times when you may want to use pi in Excel formulas.
The pi function returns a constant number, so it doesn’t require any arguments. If you try to expand the number of decimals in the cell containing pi, any digits beyond the first 14 decimal places will be all zeroes. And although Excel can display 30 decimal points in a single cell value, it’s precision is limited to 15 figures. Since pi is an irrational number, there is no limit to the number of decimals in it’s exact value. …and Excel returns the value of pi approximated to 15 figures, or 3.14159265358979. In that case you can type in any blank cell: The pi function can be found in the Math & Trig menu of Excel’s Formula tab:īut, unless you really like clicking in menus, you’d probably prefer to type the formula in a cell. Unless you’re the guy who memorized pi to over 70,000 digits, you can use a function to work with pi in Excel, instead of typing the number from memory.
