Parameters
Number
Exponent
The parameter can be indicated either directly as a number or as a variable
of the type Number. If the parameter does not correspond to the expected
type, it will automatically be converted to this. If this is not possible, the
result of this operation is given as invalid.
Examples
Exp(1.5) = 4.48169
Exp('CV.AverageTemp') = Power of the exponent (common variable
CV.AverageTemp) for base e
2.4.4.5.2 Natural logarithm
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Ln(number)
Gives the logarithm of the entered number for base e. Alternative notation
for y = loge(number), whereby
e
is the Euler number (e = 2.71828…).
Parameters
Number
> 0
The parameter can be indicated either directly as a number or as a variable
of the type Number. If the parameter does not correspond to the expected
type, it will automatically be converted to this. If this is not possible, the
result of this operation is given as invalid.
Examples
Ln(3) = 1.09861
Ln('CV.AverageTemp') = Natural logarithm of the value of the common
variable CV.AverageTemp for base e
2.4.4.5.3 Common logarithm
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Log(number)
Gives the logarithm of the entered number for base 10. Alternative notation
for y = log
10
(number).
