Natural Logarithm

Computes the natural base e logarithm of x. If x is 0, ln(x) is –. If x is not complex and is less than 0, ln(x) is NaN. The connector pane displays the default data types for this polymorphic function.

x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
ln(x) is of the same numeric representation as x.
