Default logical expression help please - for example ........

Shane,

OK thanks but...In that case why does 123 return TRUE ?.

12 is FALSE,

giving FALSE3

= TRUE ?????

why is FALSE3 True ?

Sorry I must be daft I don't understand. What are the 'number values' of
TRUE and FALSE ??

Hi,

Here is what is going on:

Suppose =1<2<3 is your formula

Excel starts on the left and evaluates 1<2 which is TRUE, next it
evalueates
TRUE<3 and returns FALSE. It never evaluates 2<3 in this example.

If this helps, please click the Yes button.

Cheers,
Shane Devenshire

Hello,

What does the logical expression (A1<A2<A3<A4) return ?

How is the expression evaluated ?

I've tried various numbers in A1....A4, but cannot seem to make sense
of
what the expression is doing ?


Thanks

KK



For example, the expression (1<2<3) evaluates to FALSE (though it would
appear to be true, and (123) evaluates to TRUE, though it would seem to
be
false.

If we convert the logic values TRUE and FALSE to numeric values (e.g.
--(A1A2)), we get 1 and 0 respectively.

But apparently, the reverse is not true. Try computing =(A1=FALSE)
and =(A1=TRUE), where A1 is any numeric or text value. The result is
always FALSE. And only TRUEFALSE, FALSE<TRUE, TRUE=TRUE and
FALSE=FALSE are TRUE.

Apparently, we can only meaningfully compare logic values with other
logic values.
