ln

The ln function returns a value or range of values consisting of the natural logarithm (base e) of each number in the specified range.

Syntax

ln(numbers)

The numbers argument can be a scalar or range of numbers. Any missing value or text string contained within a range is ignored and returned as the string or missing value.

For ln(x):

x < 0 returns an error message, and

x = 0 returns -∞

The largest value allowed is approximately x < 10³⁰⁹.
