====== Log10 ======

The **Log10** function returns the common logarithm (base 10) of a numeric value. It is frequently used in engineering units like decibels (dB), pH levels, or any system where data scales by powers of 10.



For the best precision, use the ''Single'' data type. **Note:** Similar to the natural log, the input value **B** must be greater than zero ($B > 0$).

Example
<code xbasic>
Dim A As Single
Dim B As Single
B = 100.0
A = Log10(B)    ' Returns 2.0 (because 10^2 = 100)
</code>

==== Explanation: ====
  * **B**: A positive numeric value ($B > 0$).
  * **Log10 B**: Calculates the base-10 logarithm.
  * **A**: Stores the result.
