NAME
       clog2(), clog2f(), clog2l(), clog2w(), clog2q() - complex base-2 logarithm functions

SYNOPSIS
DESCRIPTION
       returns	the  complex  base-2 logarithm of z in the range of a strip mathematically unbounded along the real axis and in the interval along
       the imaginary axis.  There is a branch cut along the negative real axis.

       is a version of it takes a argument and returns a result.
