46 General program functions
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
