FXTRACT  Extract Exponent and Significand     Exception Flags: I

FXTRACT

       Logic:      T1 . exponent(ST)
                   T2 . significand(ST)
                   ST . T1
                   push stack
                   ST . T2

     FXTRACT extracts the exponents and significand of the value in ST. It
     leaves the exponent in ST(1) and the significand in ST.

        Note:          FXTRACT is often useful with FBSTP. It can convert
                       numbers from real to decimal representation. Note also
                       that the exponent generated by FXTRACT is the true
                       exponent, not the biased exponent used internally by
                       the 80x87.
