tiBase 1.1
2.4.4.5 Arithmetical functions
2.4.4.5.1 Exponential function
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Exp(number)
Calculates e ^ number. Other notation for y = e (number) , whereby e is the
Euler number (e = 2.71828…).
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 expec-
ted 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 nota-
tion 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 expec-
ted 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
