# 471 Indexing a Float Field on Certain Values Causes a Floating Point Error Exception

---

I've managed to create a simple project that causes an "Invalid floating point operation". The program consistently fails when posting record 160 to the output file. A key factor seems to be including a floating point field in an index. I noticed that you have a technical bulletin on your web site about problems of this type. I don't have any of the printer drivers mentioned installed on my machine. In fact, on one machine I did a fresh install of Win98 Second Edition and I haven't loaded any printer drivers yet. This program fails on both my laptop running Win98 SE and my desktop machine under Win2K RC2 and Win98 SE (freshly installed in a separate partition). I'm using DBISAM Full Version 1.16 under Delphi 5.
