Calculate the log2 x logarithm of a real number find log base 2 of a number.
Floor log2 3.
3 32 log 2096 11 027 and then from here i can see that that floor 11 and ceiling 12 so ceiling x floor x 1 but when i review my answer i am incorrect usually due to how i calculate log2 2096.
When computing the base 2 logarithms of complex elements in x log2 ignores their imaginary parts.
When compiling cross compilers with gcc 4 i get redefinition errors for floor log2 and exact log2 i am working on the m6812 elf cross compiler but i am using the avr gcc one in this report as it is part of fedora and there is a srpm that was known to work.

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.
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.
