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 automati-
cally interpreted as 1 (true)
Text Text Number "Metrohm" OR "AG" --> 1
"" OR "Metrohm" --> 1
"" OR "" --> 0
An empty character string ("") is inter-
preted as 0 (false), everything else as 1
(true). The first operation therefore cor-
responds to 1 OR 1 --> 1
Time Time Number Time(1999;10;07) OR
Time(1964;02;03) --> 1 Time(): see Time(Date)
Operands of a different type: The operand which does not correspond to the result type is converted to the rele-
vant result type before the operation.
Number Text Number 1.2 OR "1.2" --> 1
0 OR "" --> 1
Before the operation, the operand of
the Number type is converted to the
Text type, as a conversion from Text to
Number is not useful. During the sec-
ond operation, the 0 is therefore con-
verted 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 Date/Time type is converted to
Number and all dates since December
30, 1899 are interpreted as 1 (true).
Time Number Number Time(1999;10;7) OR 2.5 --> 1 The same rules apply here as for the pre-
vious operation.
Text Time Number "Metrohm" OR
Time(1999;10;7) --> 1 Before the operation is carried out, the
operand of the Date/Time type is con-
verted to the Text type, and every non-
empty character string is interpreted as
1 (true).
Time Text Number Time(1999;10;7) OR
"Metrohm" --> 1 The same rules apply here as for the pre-
vious operation.
