Operand1 Operand2 Result Example Remarks
0 converted to the type Text and each
non-empty character string is inter-
preted as
1 (true).
Time Text Number Time(1999;10;7) AND
"Metrohm" --> 1 The same rules apply here as for the
previous operation.
OR
Syntax
Operand1 OR Operand2
The operands can either be entered directly or as a Variable and can be
of the type
Text , Number or Date/Time . The result type is always a number ( 1
= true, 0 = false). The following cases are possible:
Operand1 Operand2 Result
1 1 1
0 1 1
1 0 1
0 0 0
Examples
Operand1 Operand2 Result Example Remarks
Operands of the same type:
Number Number Number
5 OR 4 --> 1
4 OR 0 --> 0 Numbers larger than 1 are auto-
matically interpreted as 1 (true).
Text Text Number "Metrohm" OR "AG" --> 1
"" OR "Metrohm" --> 1
"" OR "" --> 0
An empty character string ( "" ) is
interpreted as 0 (false), everything
else as 1 (true). This means that the
first operation corresponds to 1 OR
1 --> 1
Time Time Number Time(1999;10;07) OR
Time(1964;02;03) --> 1 Time() : see function Time(Date)
Operands of different types: the operand that does not correspond to the type of result is converted
to the particular result type before the operation.
Number Text
Number 1.2 OR "1.2" --> 1
0 OR "" --> 1
Before the operation an operand of
the type
Number is converted to the
type Text , as the conversion from
Text to Number makes no sense.
This means that in the 2
nd
operation
the 0 is converted to "0" , which cor-
responds to the logical value 1 (true)
as every non-empty character string
is interpreted as 1.
Text Number Number "Metrohm" OR 1.2 --> 1 The same rules apply here as for the
previous operation.
