Base 2 logarithm and dissect floating-point numbers into exponent and mantissa

C++ Prototype

mwArray log2(const mwArray &X);
mwArray log2(mwArray *E, const mwArray &X);

C++ Syntax

#include "matlab.hpp"

mwArray X;             // Input argument(s)
mwArray E;             // Output argument(s) 
mwArray Y, F;          // Return value

Y = log2(X);
F = log2(&E,X);

MATLAB Syntax

Y = log2(X)
[F,E] = log2(X)
