Owning Palette: Exponential Functions
Requires: Base Development System
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.
|x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.|
|ln(x+1) is of 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 arctan2(b, a + 1)
Refer to the Exponential VI in the labview\examples\Mathematics\Elementary & Special Functions\Exponential Functions directory for an example of using the Natural Logarithm (Arg +1) function.
