and2 Result Example Remark
Operands of a different type:
Number Text Number 1.2 > "Metrohm" --> 01.23 >
"1.2" --> 1 Before the relational operation, the Num-
ber is converted to Text, afterwards the
texts are compared according to ASCII
value (see Chapter 2.3.4.10, page 66).
Text Number Number "Metrohm" > 1.2 --> 1 The same rules apply here as for the previ-
ous operation.
Number Time Number 2.0 > Time(1999;10;07) --> 0 Before the comparison, the operand is
converted from Date/Time to a Number.
Time Number Number Time(1999;10;07) > 2.0 --> 1 The same rules apply here as for the previ-
ous operation.
Text Time Number "Metrohm" >
Time(1999;10;07) --> 1 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 66).
Time Text Number Time(1999;10;7) >
"Metrohm" --> 0 The same rules apply here as for the previ-
ous operation.

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).

Text Text Number "Metrohm" >= "AG" --> 1 When making a comparison between two
texts, the ASCII value of the character
string is compared (see Chapter 2.3.4.10,
page 66). Attention: Uppercase and
lowercase letters have different values!
