Operand1 Operand2 Result Example Remarks
Operands of different types:
Number Text Number
1.2 >= "1.2" --> 1
1.2 >= "Metrohm" --> 0
Before the comparative opera-
tion the
Number is converted to
Text and then the texts are
compared according to the
ASCII table.
Text Number Number
"Metrohm" >= 1.2 --> 1
The same rules apply here as
for the previous operation.
Number Time Number
2.0 >= Time(1999;10;07) --> 0
Before the comparison the
Date/Time is converted to a
Number (see Type conversion
"TimeToNumber").
Time Number Number
Time(1999;10;07) >= 2.0 --> 1
The same rules apply here as
for the previous operation.
Text Time Number
"Metrohm" >=
Time(1999;10;07) --> 1
Before the operation an oper-
and of type
Date/Time is con-
verted to
Text (i.e.: "1999-10-07
00:00:00 UTC+2"
) and then the
texts are compared according
to the ASCII table.
Time Text Number
Time(1999;10;7) >= "Metrohm"
--> 0
The same rules apply here as
for the previous operation.

In a comparison between two
texts the ASCII values (see
ASCII table) of the character
strings are compared. Note:
upper and lower case letters
have different values!
