Hi Bruce,

Quite honestly, I paste this tag on all of my created CFs. Seeing that the phrase has become obsolete as of 2000, I'm removing it. However, these 'reserved rights' are what allow us to freely distribute our CFs in the first place! :)

Hi all

I have a small add to this Function:
If I choose 0 Decimals, then I don't like for Example 35'000.
I would like to have 35'000
without a Point on the End....
Here the Solution: (only the last couple Lines
-------------------------------------------------------------------- ------
Case (
// No parameters specified...
decimals = "" AND dec_point = "" AND thousands_sep = "" ;
number ;
// No decimal requested
decimals = 0;
// Else
dollars & dec_point & cents
--------------------------------------------------------------------- -----
Anyhow Bruce Thanks for this great Function!

Hi Matthias,

I implemented your good suggestion and made another improvement to include negative decimals - similar to the way the Round ( ) function works.

This doesn't work with non english langauges, at least those whose native decimal separateor are not .

Your code assumes that the number have their decimal separator as a dot. If you use Filemaker on a french OS, then FMP internal decimal separator wil be the comma.

So you have to avoid this assumption in your code.

Moreover an option to avoir 129,00 when the nulber is just 129 would be nice

Just a warning not to use this function with numbers containing leading zeros (typically stored as a text field). This function will strip leading zeros from those numbers.
