-* Fast approximation to the log2() function.  It uses a two step
-* process.  First, it decomposes the floating-point number into
-* a fractional component F and an exponent E.  The fraction component
-* is used in a polynomial approximation and then the exponent added
-* to the result.  A 3rd order polynomial is used and the result
-* when computing db20() is accurate to 7.984884e-003 dB.
