Examples
Log(10) = 1
Log('CV.AverageTemp') = Common logarithm of the value of the com-
mon variable CV.AverageTemp
2.3.4.5.4 Square root
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Sqrt(number)
Returns the square root of the entered number. Alternative notation for y
= √ number or y =
2 √ number.
Parameters
Number
≥ 0
The parameter can be indicated either directly as a number or as a variable
of the Number type. If the parameter does not correspond to the
expected type, it will automatically be converted to it. If this is not possi-
ble, the result of this operation is returned as invalid.
Examples
Sqrt(33) = 5.745
Sqrt('CV.AverageTemp') = Square root of the value of the common
variable CV.AverageTemp
2.3.4.5.5 Absolute value
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Abs(number)
Returns the absolute value of the entered number, i.e. the value of the
number irrespective of its sign.
Parameters
Number
The parameter can be indicated either directly as a number or as a variable
of the Number type. If the parameter does not correspond to the
expected type, it will automatically be converted to it. If this is not possi-
ble, the result of this operation is returned as invalid.
Examples
Abs(–55.3) = 55.3
Abs('CV.AverageTemp') = Value of the common variables CV.Avera-
geTemp without signs
