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).

"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) >=

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).

"Metrohm" >= 1.2 --> 1

The same rules apply here as for the previ-
ous operation.

2.0 >= Time(1999;10;07) -->

Before the comparison, the operand is con-
verted from the type Date/Time to a
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)
.
