Logical Operators
(Redirected from Or)
The logical operators, And, Or, and Not, are used to combine Boolean values. Analytica uses the values True = 1
and False = 0
.
When applied to values other than 0
or 1
, other parameter values are interpreted as follows:
- a non-zero numeric is treated as true
- NaN is treated as ambiguous (could be
0
or1
) - Null results in a warning, with a Null result.
- Any other data type results in an error.
A And B
True if both «A» and «B» are true. False if either «A» or «B» is false.
In this table, «x» signifies a numeric value that is not equal to zero (and is not NaN).
And 0 x NaN Null 0 0 0 0 Null x 0 1 NaN Null NaN 0 NaN NaN Null Null Null Null Null Null
A Or B
True if «A» or «B», or both, are true.
In this table, «x» signifies a numeric value that is not equal to zero (and is not NaN).
Or 0 x NaN Null 0 0 1 NaN Null x 1 1 1 Null NaN NaN 1 NaN Null Null Null Null Null Null
Not A
True if «A» is false.
Not 0 x NaN Null 1 0 NaN Null
