The problem is not with the math coprocessor, but the software
used by mathematica in computing range reduction.  To reduce
the range of 2^100  you need about 120 bits of Pi.  If Mathematica
is supposed to provide a seamless "mathematical" computational
environment, it should not give wrong answers and allege that they
have high Accuracy and Precision.
