LB (Number)

Description

This function shows the logarithm value of base 2.
In $LB(Number)$ , $Number$ is any positive real number.
LB means the logarithm with the base 2.
So the Binary logarithm is the logarithm to the base 2.
The Binary logarithm function is the inverse function of the power of two function.
So for any real number x, $x=log_{2}n$ , $2^{x}=n$ .
For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1, the binary logarithm of 4 is 2, and the binary logarithm of 32 is 5.
This function will return the result as NaN when the given number as negative.
