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

Dim A As Single
Dim B As Single
B = 2.718282
A = Log(B)      ' Returns approx. 1.0

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