Text Number Number "Metrohm" = 1.2 --> 0 The same rules apply here as for the previous
operation.
Number Time Number 2.0 = Time(1999;10;07) -->
0 Before the relational operation, the operand
of the Date/Time type is converted to a
Number. During execution of the operation,
the exact value is always used after this con-
version, even if maximum 5 places after the
comma can be displayed (see Chapter
2.3.4.7.5, page 68).
Time Number Number Time(1999;10;7) = 2.0 --> 0 The same rules apply here as for the previous
operation.
Text Time Number "Metrohm" =
Time(1999;10;07) --> 0 Before the operation, the operand is con-
verted from Date/Time to Text (in this
example: "1999-10-07 00:00:00 UTC
+2"), afterwards the texts are compared
according to ASCII value (see Chapter
2.3.4.10, page 75).
Time Text Number Time(1999;10;07) =

Operand1 > Operand2
The operands can be entered either directly or as a variable and can be of
the Text, Number or Date/Time type. The result type is always a num-
ber (1 = true, 0 = false).

Operands of the same type:
Number Number Number 5 > 4 --> 1
4 > 5 --> 0
–
Text Text Number "Metrohm" > "AG" --> 1
"Aarau" > "Zug" --> 0
When making a comparison between two
texts, the ASCII value of the character
string is compared (see Chapter 2.3.4.10,
page 75). Attention: Uppercase and
lowercase letters have different values!
