| The current version (as of 01/17/2011) fails with the following input: FormatPercent( .1304 ; 1 ). It'll return 1300% instead of 13.0%. The issue has to do with the ending case statement, where the rounded percent - integer of the rounded percentage happens to equal 0, instead of some decimal (say: 13.0 - 13). The function will attach zeros to the whole number portion of the percentage without a decimal. Here's a fixed version of the function: Case ( Decimals = 0 or IsEmpty ( Decimals ) ; Int ( Round ( Number * 100 ; 0 ) ) ; Int ( Round( Number * 100 ; Decimals ) ) & Case ( ( Number * 100 ) = Int ( Number * 100 ) ; Left ( ".0000000000" ; Decimals + 1 ) ; Round ( Number * 100 ; Decimals ) - Int( Round ( Number * 100 ; Decimals ) ) = 0 ; Left ( ".0000000000" ; Decimals + 1 ) ; Left ( Round ( Number * 100 ; Decimals ) - Int( Round ( Number * 100 ; Decimals ) ) & "0000000000" ; Decimals+1 ) ) ) & "%" |

| It would be cool if this could be modified to accept a minimum decimal and a maximum decimal parameter, where the minimum would be used in cases where the number is an integer and max is for a non-integer. E.g. I'd prefer to display "50%" or "50.00%" rather than "50.000000%", but if the numeber is non integer I would want to see 6 decimal places, such as "3.056214%". | ||

| Tom - To achieve the result you are looking for, simply replace the first "Result" text - Left ( ".0000000000" ; Decimals + 1 ) - in the second Case statement (3rd line of the calculation) with empty quotes. | ||
