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 --> 0
4 < 5 --> 1
-
Text Text Number "Metrohm" < "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 66). Attention: Upper-
case 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 54)
Operands of a different type:
Number Text Number 1.2 < "Metrohm" --> 11.2 <
"1" --> 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 --> 0 The same rules apply here as for the previ-
ous operation.
Number Time Number 2.0 < Time(1999;10;07) -->
1 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 -->
0 The same rules apply here as for the previ-
ous operation.
Text Time Number "Metrohm" <
Time(1999;10;07) --> 0 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" --> 1 The same rules apply here as for the previ-
ous operation.
