Syntax
Operand1 OR Operand2
The operands can be entered either 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 Remark
Operands of the same type:
Number Number Number 5 OR 4 --> 1
4 OR 0 --> 1
Numbers greater than 1 are automatically
interpreted as 1 (true)
Text Text Number "Metrohm" OR "AG" --> 1
"" OR "Metrohm" --> 1
"" OR "" --> 0
An empty character string ("") is interpre-
ted as 0 (false), everything else as 1 (true).
The first operation therefore corresponds
to 1 OR 1 --> 1
Time Time Number Time(1999;10;07) OR
Time(1964;02;03) --> 1 Time(): see Time(Date)
Operand of different type: The operand which does not correspond to the result type is converted to the relevant
result type before the operation.
Number Text Number 1.2 OR "1.2" --> 1
0 OR "" --> 1
Before the operation, the operand of the
type Number is converted to the type
Text, as a conversion from Text to
Number is not advisable. During the sec-
ond operation, the 0 is therefore conver-
ted to "0", which corresponds to the
logical value 1 (true), as every character
string that is not empty is interpreted as
1.
Text Number Number "Metrohm" OR 1.2 --> 1 The same rules apply here as for the pre-
vious operation.
Number Time Number 2.0 OR Time(1999;10;7) --> 1
0 OR Time(1964;02;03) --> 1
Before the operation, the operand of the
type Date/Time is converted to Num-
ber and all data from December 30, 1899
are interpreted as 1 (true).
