====== Log ======

The **Log** function returns the natural logarithm (base $e \approx 2.718$) of a numeric value, often denoted as **ln(x)**. It is widely used in calculations involving exponential decay, growth rates, and complex sensor data scaling.

For the most accurate results, use the ''Single'' data type. **Note:** The input value **B** must be greater than zero ($B > 0$). Entering zero or a negative number will result in a runtime error.

Example
<code xbasic>
Dim A As Single
Dim B As Single
B = 2.718282
A = Log(B)      ' Returns approx. 1.0
</code>

==== Explanation: ====
  * **B**: A positive numeric value ($B > 0$).
  * **Log B**: Calculates the natural logarithm ($ln B$).
  * **A**: Stores the result.
