Operand1 Operand2 Result Example Remarks
Number Time Number 2.0 = Time(1999;10;07) --> 0 Before the comparative operation
the Date/Time is converted to Num-
ber . When the operation is carried
out the exact value obtained after
this conversion is always used, even
when only a maximum of 5 decimal
places can be shown (for details
please refer to Type conversion
"TimeToNumber", Note).
Time Number Number Time(1999;10;7) = 2.0 --> 0 The same rules apply here as for the
previous operation.
Text Time Number "Metrohm" =
Time(1999;10;07) --> 0 Before the operation an operand of
type
Date/Time is converted to Text
(i.e.: "1999-10-07 00:00:00 UTC+2" ),
then the texts are compared accord-
ing to the ASCII table.
Time Text Number Time(1999;10;07) =
"Metrohm" --> 0 The same rules apply here as for the
previous operation.

Operands of the same type:
Number Number Number 5 > 4 --> 1
4 > 5 --> 0 -
Text Text Number "Metrohm" > "AG" --> 1
"Aarau" > "Zug" --> 0
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!
Time Time Number Time(1998;04;06) >
Time(1964;02;03) --> 1 Time() : see function Time(Date)
Operands of different types:
Number Text
Number 1.2 > "Metrohm" --> 0
1.23 > "1.2" --> 1 Before the comparative operation 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.
