returned.Improvements in Excel 2010The Erf function has been improved in Excel 2010 in that it can now accept negative function arguments.In Excel 2007 or earlier, if you input a how to use erf function in excel negative value for the upper or lower limit, the function would return an error. However, in Excel 2010, the function algorithm has been improved, so that it can now calculate the function for both positive and negative ranges.Erf Function ExamplesIn the following spreadsheet, the Excel Erf function is used to calculate the Error Function integrated between different limits.Formulas:AB1=ERF( erfinv excel 0, 1.5 )- error function integrated between 0 & 1.5 2=ERF( 1.5 )- error function integrated between 0 & 1.5 3=ERF( 1, 2 )- error function integrated between 1 & 2 Results:AB10.966105146- error function integrated between 0 & 1.5 20.966105146- error function integrated between 0 & 1.5 30.152621472- error function integrated between 1 & 2 Note that, in the above spreadsheet, the functions in cells A1 and A2 perform the same calculation - i.e. the integral between 0 and 1.5.Further examples of the Excel Erf function are provided on the Microsoft Office website.Erf Function ErrorsIf you get an error from the Excel Erf function this is likely to be one of the following:Common Errors#NUM!-Occurs in older versions of Excel (Excel 2007 or earlier), if one or both of the supplied arguments are negative.#VALUE!-Occurs if one or both of the supplied arguments are non-numeric.

Join them; it only takes a minute: Sign up Using Excel Formula functions (ERF, ERFC) in Excel VBA code? up vote 3 down vote favorite I'm trying to use the error function and the complimentary error function in my program. Neither are working. I keep getting the error Compile Error: Sub or error function Function not defined. However, if I go into a cell and manually try to use the error function, it works. Why is that? How can I use it in my actual code? The error function is ERF(x) and the complimentary error function is ERFC(x). Here's an example of things that don't work: Sub SeriouslyWHYIsntThisWorking() x = 3 Range("A1") = Erf(x) End Sub Even this doesn't work: Sub PleaseWork() Range("A1") = Erfc(1) End Sub But if I went into Excel and typed =ERF(3) or =ERFC(1) into error function in a cell, it'll work. I'm very new to this and probably missing something incredibly simple. Help would be greatly appreciated! excel vba excel-vba share|improve this question edited Jul 23 '12 at 21:31 Gaffi 3,13162859 asked Jul 23 '12 at 21:04 TheTreeMan 32161429 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted To use a worksheet formula in vba, you need to put Application.WorksheetFunction. in front of it.

(Look for atpvbaen.xls) The ERF function is part of that add-in, and there are two versions of it (one for use in Excel functions, and one for VBA), and you'll need the right one set up and referenced by your project to be usable. The add-ins are standard from MSFT, but not always set up by
