The natural logarithm of input variable
x1
is formed.
The basis of natural logarithms is constant e (2,71828182845904).
If
x1
is not wired, this is interpreted as
x1
= 1. In this case
y1
is 0.
With a negative input variable
x1
,
y1
= -1,5

Note:
LN is the reversal function of function EEXP.
Examples:
The result of input value
x1
= 63 is an output value of
y1
= 4,143134726.
The result of input value
x1
= 2,71828182845904 is an output value of
y1
= 1.
