rounding a double value to n decimal places

[p3aul]

I have a variable of type double that I want to display in an edit box. after I do my calculations I am left with a number that has about 10 decimal places and I want to reduce it to 3 decimal places. How Do I do this?
TIA,
Paul

Use the [blue]FormatFloat[/blue] function.
Usage : [green]FormatFloat('#,##0.00', myValue)[/green]

From the help files: "The number being formatted is always rounded to as many decimal places as there are digit placeholders ('0' or '#') to the right of the decimal point."

Anywhere you place a Zero, it will always display at least a zero there. Anywhere you place a (number / pound) sign will be filled if a value is there.
The usage showed above will show tousands, separated by comma (or millions, or more, all with commas for every 3 places) if the value is that large. Also above, will always display 2 places after the decimal. Just add another zero and you are rounding to 3 decimal places.

In the help files there is a lot more on this function.
Hope this helps.

Don't take life too seriously, its not permanent anyways.

Thanks, Opieo, I slept on it and decided to change my edits to mask edits and that solved my problem!
