Operand1 Operand2 Result Example Remarks
Number Time Number
2.0 <= Time(1999;10;07) --> 1
Before the comparison the
Date/Time is converted to a
Number (see Type conversion
"TimeToNumber").
Time Number Number
Time(1999;10;07) <= 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 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"
--> 1
The same rules apply here as
for the previous operation.
Unequal
Syntax
Operand1 <> Operand2
The operands can either be entered directly or as a Variable and can be
of the type
Text, Number or Date/Time. The result type is always a number (1
= true,
0 = false).

Operands of the same type:
Number Number Number
5 <> 4 --> 1
5 <> 5 --> 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!
Text Text Number
"Metrohm" <> "AG" --> 1

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 <> "1.2" --> 0
1.2 <> "Metrohm" --> 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.
Number Time Number
2.0 <> Time(1999;10;07) --> 1
Before the comparison the
Date/Time is converted to a Num-
ber
(see Type conversion "Time-
ToNumber").
Time Number Number
Time(1999;10;07) <> 2.5 --> 1
The same rules apply here as for
