LOG10(n)

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.
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).

=log 10(5)= 0.698970004
=log(55)= 1.740362689
=log(10)= 1
=log(1)= 0
=log(-10)= NaN
=log(0.25)= -0.602059991
