Calculate the log2 x logarithm of a real number find log base 2 of a number.
Floor log2 3.
First by using a scientific calculator calculating what log2 2096 is by.
In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
When computing the base 2 logarithms of complex elements in x log2 ignores their imaginary parts.
For example and while.
The number of digits in the binary representation of a positive integer n is the integral part of 1 log 2 n i e in information theory the definition of the amount of self information and information entropy is often expressed with the binary logarithm corresponding to making the bit the fundamental unit of information.
For the syntax f e log2 x any zeros in x produce f 0 and e 0 input values of inf inf or nan are returned unchanged in f with a corresponding exponent of e 0.
