type then it will be automatically converted to it (see Type conversion
"TextToNumber"). If this is not possible then "
invalid " will be returned as the
result of this operation.
Examples
Log(10) = 1
Log('CV.MeanTemp') = common logarithm of the value of the Common vari-
able
Square root
Syntax
y = sqrt(Number)
Returns the square root of the entered number. Another way of writing y =
√
Number or y = 2 √ Number .
Parameter
Number >=0
The parameter can either be entered directly as a number or as a Variable
of the type
Number . If the parameter does not correspond to the selected
type then it will be automatically converted to it (see Type conversion
"TextToNumber"). If this is not possible then " invalid " will be returned as the
result of this operation.
Examples
Sqrt(33) = 5.745
Sqrt('CV.MeanTemp') = square root of the value of the Common variable
Absolute value
Syntax
y = Abs(number)
Returns the absolute value of the entered number, i.e. the value of the
number irrespective of its sign.
Parameter
Number
The parameter can either be entered directly as a number or as a Variable
of type
Number . If the parameter does not correspond to the selected type
then it will be automatically converted to it (see Type conversion "TextTo-
Number"). If this is not possible then "
invalid " will be returned as the result of
this operation.
Examples
Abs(-55.3) = 55.3
Abs('CV.MeanTemp') = value of the Common variable without sign
Fraction
Syntax
y = Frac(number)
Returns the fractional part of the entered number.
