Exponential function
Syntax
y = exp(number)
Calculates e ^ Number . Another way of writing y = e (number) , where e is the
exponential (e = 2.71828...).
Parameter
Number Exponent
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
Exp(1.5) = 4.48169
Exp('CV.MeanTemp') = potential of the exponent (Common variable) based
on e
Natural logarithm
Syntax
y = ln(number)
Returns the logarithm of the entered number based on e. Another way of
writing y = log
e
(Number), where e is the exponential (e = 2.71828...).
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
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).
