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).
Examples
Oper-
and1 Oper-
and2 Result Example Remark
Operands of the same type:
Number Number Number 5 >= 4 --> 1
4 >= 5 --> 0
-
Text Text Number "Metrohm" >= "AG" --> 1 When making a comparison between two
texts the ASCII value of the character
sequence is compared (see Chapter
2.4.4.10, page 66). Attention: Upper-
case and lowercase letters have different
values!
Time Time Number Time(1998;04;06) >=
Time(1964;02;03) --> 1 (see Chapter 2.4.4.6.2, page 54)
Operands of a different type:
Number Text Number 1.2 >= "1.2" --> 11.2 >=
"Metrohm" --> 0 Before the relational operation, the Num-
ber is converted to Text, afterwards the
texts are compared according to ASCII
value (see Chapter 2.4.4.10, 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 con-
verted from the type 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 the type Date/Time to Text
(here thus: "1999-10-07 00:00:00 UTC
+2"), afterwards the texts are compared
according to ASCII value (see Chapter
2.4.4.10, page 66).
Time Text Number Time(1999;10;7) >=
"Metrohm" --> 0 The same rules apply here as for the previ-
ous operation.
