Operand1 Operand2 Result Example Remark
Text Time Number "Metrohm" OR
Time(1999;10;7) --> 1 Before execution of the operation, the
operand of the type Date/Time is con-
verted to the type Text and every char-
acter string that is not empty is interpre-
ted as 1 (true).
Time Text Number Time(1999;10;7) OR
"Metrohm" --> 1 The same rules apply here as for the pre-
vious operation.

Syntax
Operand1 = 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 num-
ber (1 = true, 0 = false).

and2 Result Example Remark
Operands of the same type:
Number Number Number 5 = 5 --> 1
4 = 5 --> 0
-
Text Text Number "Metrohm" = "AG" --> 0
"aG" = "AG" --> 0
When making a comparison between two
texts the ASCII value of the character
sequence is compared (see Chapter
2.4.4.10, page 87). Attention: Uppercase
and lowercase letters have different values!
Time Time Number Time(1998;04;06) =
Time(1964;02;03) --> 0 (see Chapter 2.4.4.6.2, page 75)
Operands of a different type:
Number Text Number 1.2 = "1.2" --> 11.2 =
"Metrohm" --> 0 Before the relational operation, the Number
is converted to Text, afterwards the texts
are compared according to ASCII value (see
Chapter 2.4.4.10, page 87).
Text Number Number "Metrohm" = 1.2 --> 0 The same rules apply here as for the previous
operation.
