Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This function formats numbers for use in text strings or calculations with a text result. It's especially useful when there are multiple numbers in a text string and at least one must be displayed in a different format than the others. It works on numbers of any length, and produces its result without recursion.

Separator and Currency parameters are optional.

Decimal parameter defaults to "." or "," (based on localization) unless rounding is <= 0, in which case it's omitted.

Precision defaults to 2 if parameter is not a digit or is unspecified.

UPDATED 11.20.2009

Added " + 0" to declaration of "n" variable to deal with cases where the number parameter is null or empty.

UPDTED 09.10.2015

Fixed a bug that resulted in malformed numbers ( like "€10..05,05" ) in some European FMP 12 (and higher) files.

Modified Decimal to use the correct integer/fraction separator [ "." or "," ] for the file's region when the decimal parameter is null.

I am using your wonderful calculation but made a mistake somewhere. When i enter an amount i get a number of zeros after the desired amount: $175.2300000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 Any way you can tell me where i messed up? Let ( [ t = Int ( GetAsNumber ( amount_paid ) ) ; prec = Case ( Length ( t ) ; t ; 2 ) ; dec = Case ( Length ( "." ) ; "." ; "." ) ; n = Round ( amount_paid + 0 ; prec ) ; sgn = Case ( n < 0 ; "-" ) ; n = Abs ( n ); x = NumToJText ( n ; 1 ; 0 ) ; y = NumToJText ( n * 10^prec ; 0 ; 0 ) ; z = Position ( x ; "." ; 1 ; 1 ) ] ; sgn & "$" & Substitute ( Case ( z = 1 ; 0 ; z ; Left ( x ; z - 1 ) ; x ) ; [ "," ; "." ] ) & Case ( prec > 0 ; dec & Right ( 10^prec & y ; prec ) ) ) Thanks |

Chris: The value of "t" is the precision, so you're rounding to a number of decimal places equal to the integer value of the number you're formatting. Geoff |

Fabulous, thank you. Just what I've been looking for. In cases where my number field is empty I'd like to be able to strip out the currency symbol in the output, but I can't work out how to amend the calc to do this. Eg */ Let ( [ t = Int ( GetAsNumber ( 2) ) ; prec = Case ( Length ( t ) ; t ; 2 ) ; dec = Case ( Length ( "." ) ; "." ; "." ) ; n = Round ( Flights Total + 0 ; prec ) ; sgn = Case ( n < 0 ; "-" ) ; n = Abs ( n ); x = NumToJText ( n ; 1 ; 0 ) ; y = NumToJText ( n * 10^prec ; 0 ; 0 ) ; z = Position ( x ; "." ; 1 ; 1 ) ] ; sgn & Currency & Substitute ( Case ( z = 1 ; 0 ; z ; Left ( x ; z - 1 ) ; x ) ; [ "," ; "," ] ) & Case ( Flights Total â‰¤ 0 ; ""; prec > 0 ; dec & Right ( 10^prec & y ; prec ) ) ) Any ideas much appreciated. Thanks million |

Changing the line... sgn & Currency & ...to... sgn & Case ( Length ( number ) ; Currency ) & ...should do it. |

Yep, that's done it. Thanks so much for this, I've been trying to create this for, well, years! I finally have a multi-currency invoice system that only shows items with a value. Hugely appreciated! |

Hiho over there, tried this function but found out, that it doesn't work with the language systems where the Standard decimal is "," and the thousand sep is "." E.g. if I have 654,21 EUR it converts to EUR654..21,21 Too weird for me to find a soultion, please help... Thanks, Roland |

It has worked for others using the notation you described, so i wonder what's different in your use case.... If you're willing to put together a sample file, I'd be glad to look at it--even if just to satisfy my own curiosity. Just two fields would be needed--a number field for the raw input and a calc field that shows what values (if any) you've assigned for each parameter. The link to my web site on the CF page shows my email address. |

Very handy function. Could it work with a repeating text field (i.e. the output of an ExecuteSQL call)? Thanks, Barney. |

Hi ! Thanks for sharing, but unfortunately I ran into the same problem as Roland from Berlin; I'll put an example together and mail it. Best, Ernst info <at> clineco.nl |

Thank you so much! This is a great and necessary function. Any idea why FileMaker hasn't provided this as a standard feature? | ||

Much appreciated. Just what I needed to correctly format currency amount totals within a text calculation field. | ||

Fantastic Function!! Thank you. I am unsure how to skip using a currency symbol though. No matter what I put in there I get my system default currency. I cannot change it to $ or leave it blank. The description does say Currency is Optional. I've tried setting it as "", 0, 1, space etc. No change. MY FMP ver is 19, Windows and is up to date. EXAMPLE: FormatNumberAsText ( Sum ( Director_Shareholder::Shares ) ;0;","; 0; 0) & " Shares" (I am trying to just format using thousands separator. Calculation is used in a Menu Button) | ||

@Sean: I copy/pasted your example in my Data Viewer, replacing your number parameter and currency parameters like this... FormatNumberAsText ( 1234.99 ;"";","; 0; 0) & " Shares" ...and got "1,235 Shares" as the result. Paste your original expression in your Data Viewer, replace the 0 currency parameter value with "". If it produces the expected result (no currency symbol) in the Data Viewer, the problem is coming from field or layout object formatting. |
