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.
