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
