Dear HS,

Amazing. I fail to reproduce the error in SD calculation in the example you give, using the French version of Excel 2003 I have here. I get the correct value of 1. I'll check with another version of Excel (also French) at home tonight.

Edit: error reproduced at home with the French version of Excel 2000... Shit ! :-(

Does Microsoft also call this a "feature", rather than a bug ?

And considering the fact that the bug appears with some sets of data, but not others, validating a spreadsheet by comparison with another software or manual calculation would not be sufficient.

Regards
Ohlbe
