Function name:
LOG10

Category:
Mathematical

Summary:
Calculates the logarithm to the base 10 or common logarithm of a positive real number. The common logarithm of x is often written as log(x) or log10(x).

Syntax:
LOG10(Number)

Returns:
Returns a real number that is the common logarithm of the specified number.

Arguments:
Number is a positive real number, or a reference to a cell containing that number, that is the value for which the common logarithm is to be calculated.


 * If Number is non-numeric, then LOG10 reports a #VALUE! error.
 * If Number is less than or equal to 0, then LOG10 reports an invalid argument error (Err:502).

Additional details:

 * For any positive real number x, $$10^{\text{log}(x)}=x$$ and $$\text{log}(10^x)=x$$.


 * To convert the common logarithm of a positive real number x to a natural logarithm (base-e), use the formula $$\text{ln}(x)=\text{log}(x)~/~\text{log}(e)$$.


 * Additional information about common logarithms can be found at Wikipedia's Common logarithm page.
