=sumproduct in Excel 2000
In the following "sumproduct" function, what do the "--" mean?
=SUMPRODUCT(--('Evaluation Detail'!$B$7:$B$499<0),--('Evaluation Detail'!$F$7:$F$499="Jane Doe")) Thank you, -- LPS |

=sumproduct in Excel 2000
--('Evaluation Detail'!$B$7:$B$499<0)
returns 493 true/falses. The -- stuff changes the booleans to 1's and 0's. 'cause =sumproduct() likes to work with numbers. Bob Phillips explains =sumproduct() in much more detail he http://www.xldynamic.com/source/xld.SUMPRODUCT.html And J.E. McGimpsey has some notes at: http://mcgimpsey.com/excel/formulae/doubleneg.html LPS wrote: In the following "sumproduct" function, what do the "--" mean? =SUMPRODUCT(--('Evaluation Detail'!$B$7:$B$499<0),--('Evaluation Detail'!$F$7:$F$499="Jane Doe")) Thank you, -- LPS -- Dave Peterson |
