#include <codecogs/maths/combinatorics/arithmetic/log_inv.h>

using namespace Maths::Combinatorics::Arithmetic;

Function to compute the inverse logarithm, by feeding it with the base and the result.

Computing

$\log_{10} x = 2$

(1)

printf("Inverse logarithm of base 10 resulting 2: %d ",log_inv(10,2));

Output:

Inverse logarithm of base 10 resulting 2: 100

It will return -1 for incorrect base input ( good input goes from +1* to +infinite).

* - +1 means the first number right after 1 (ie. 1,0001).

base

Any value above 1

result

Any value (even negative)

The value to apply the logarithm operator ( log x )
