LOG10(Number)

Description

This function gives the logarithm value with the base 10.
The logarithm of x to base b is the solution y to the equation.i.e $b^{y}=x$ .
For e.g The logarithm of 1000 to base 10 is 3. Because 1000 = 10*10*10 = $10^{3}$ .
The logarithm of base 10 is called Common Logarithm or Decimal Logarithm or Decadic Logarithm.
It is denoted by $\log _{10}$ or $log(x)$ .
$\log _{10}(x)$ is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than $\log _{10}(x)$ .
For e.g:log(5260)= 3.7209, that is nearly(next digit) to 4.
That is the number of digits of 5260(4).
