Hi

I have a variable as a float. How do I restrict it to only display only 2 decimal places. At the moment it changes all the time and interfers with other text on the screen.

Thank you in advance

Don't know if there's an official way, but you could always convert it to a string and do some string manipulation to display what you want.

write a function that takes your number as an argument, changes to string, truncates any extra decimal places, returns a string to the call, display your string - This may slow you down however.

it would be nice if dbp had a "Format" Function like vb

Really easy...

newnum=int(num*100)/100

Should work...

It doesn't matter if it is confusing, as long as it works

Try this code to see if it would be useful to you

I've only lightly tested it but it should be Ok for most things.

Thank you to IanM for working out this function. Only problem it has is that it does not round off , it cuts off.

The rest of the function works well

Any ideas how to solve the rounding problem ?

modify ian's function so that before it returns the 2-digit decimal, it looks at the numeric value of it, and changes it up or down based on the number it is currently
