Computes the natural logarithm of (x + 1).
When x is near 0, this function is more accurate than adding 1 to x then using the Natural Logarithm function. If x is equal to –1, the result is –
. If x is not complex and is less than –1, the result is NaN. The connector pane displays the default data types for this polymorphic function.

Refer to the Exponential VI in the labview\examples\general\functions\Mathematics\Elementary & Special Functions\Exponential Functions directory for an example of using the Natural Logarithm (Arg +1) function.
