Re: restricting decimal places on floating point values

Use the Format command like this:
Pascal and Delphi Syntax (Toggle Plain Text)
  1. VolumeCalc.Caption := Format('%.2f',[StrToFloat(EngineSizeVal.Text) / 2 / StrToFloat(CylNumVal.Text)]);

Re: restricting decimal places on floating point values

i have just changed my Label to a EditBox.. and the above code doesnt seem to work at all, just wondering how to limit an edit box to 2 decimal places.

Pascal and Delphi Syntax (Toggle Plain Text)
  1. VolumeCalc.Text := FloatToStr(StrToFloat(EngineSizeVal.Text) / 2 / StrToFloat(CylNumVal.Text));

Re: restricting decimal places on floating point values

It should be exactly the same. Format returns a string, so there's no difference in applying the result to an Editbox or a label.
What exactly is the problem?
