Log
Calculate a logorithm, which is the power to which a base number must be raised to produce a given number.
Input Fields

input: The number to calculate the logorithm for

base: The base to use, often 10
Output Fields
 output: The power to which the base number must be raised
Examples
If input is 100
and base is 10
then output is 2
because 10^2 = 100
If input is 8
and base is 2
then output is 3
because 2^3 = 8
