Examples
Ln(3) = 1.09861
Ln('CV.MeanTemp') = natural logarithm of the value of the Common variable
based on e
Common logarithm
Syntax
y = log(number)
Gives the logarithm of the entered number to the base 10. Another way of
writing y = log
10
(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
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
