I am using a flexgrid

To format the output of my float to the grid I am using

C++

output.Format("%2.0f",value)

and this is rounding up my float(value) to an integer after this command, say value was 8.5 output is 9 which is then sent out to the flexgrid

any ideas please ?

Not a valid question. You forgot to tell us what formatting results do you want to get.
After all, learn floating-point formatting, it's just one page...

Solution 1

Your format string specifies no digits after the decimal point so it will naturally round the value. Try ...

C++

output.Format("%5.2f",value)

... and it's always a good idea to read the documentation.

Thanks Richard that worked. Found the appendix in the back of my C book, but not very helpful !

Take a look also at C-style format specifications.
