Computes the base e natural logarithm of a specified input value.
is not complex and is less than 0,
is not a number (NaN).
For very small values of
Natural Logarithm (Arg +1)
is more accurate than adding 1 to
then using this node.
An input to this operation.
This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.
Result of the operation.
This output assumes the same numeric representation as
is of the form
= a + bi, that is, when
is complex, the following equation defines the natural logarithm
) is the phase of
over the interval
. In other words, the output uses the following equation:
