Natural Logarithm (Arg + 1) (G Dataflow)

Last Modified: January 9, 2017

Computes the natural logarithm of a specified value plus 1 (x + 1).

When x is near 0, this node is more accurate than adding 1 to x then using the Natural Logarithm node. If x is equal to -1, the result is - . If x is not complex and is less than -1, the result is not a number (NaN).

x

An input to this operation.

This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.

ln(x+1)

Result of the operation.

This output assumes the same numeric representation as x. When x is of the form x = a + bi, that is, when x is complex, the following equation defines ln(x+1):
ln ( x + 1 ) = ln ( | x + 1 | ) + i arctan 2 ( b , a + 1 )
