For example: my input: 12.3 output: 000012.3 345.9 000345.9 Thanks a lot Back to top JD Guest Posted: Tue May 24, 2005 11:39 am    Post subject: Re: format question "Karim" <Karim (AT) noemail (DOT) com> wrote: Quote: is there any API to convert a string or an int to a specific format?

The Win32 API has a wsprintf() function. wich doesn't work with floating point numbers, use sprintf, works also in windows. Or use FmtStr, AnsiString::sprintf or similar formatting functions Quote: Gambit Christian Back to top Heinrich Wolf Guest Posted: Wed May 25, 2005 6:04 pm    Post subject: Re: format question "JD" <nospam (AT) nospam (DOT) com> schrieb im Newsbeitrag news:4293a9ba$1 (AT) newsgroups (DOT) borland.com... .... Quote: int WholePortion = SomeFloat; int DecimalPortion = (SomeFloat - WholePortion) * 100; Buffer.sprintf("%06d.%d", WholePortion, DecimalPortion ); That will give wrong output on e.g. SomeFloat = 25.06 ! The Format for WholePortion and DecimalPortion must be "%06d.%02d" But why for heaven's sake not: Buffer.sprintf("%06.2f", SomeFloat); ?
