%description
SymFPU is an implementation of the SMT-LIB / IEEE-754 operations in
terms of bit-vector operations.  It is templated in terms of the
bit-vectors, propositions, floating-point formats and rounding mode
types used.  This allow the same code to be executed as an arbitrary
precision "SoftFloat" library (although it's performance would not be
good) or to be used to build symbolic representation of floating-point
operations suitable for use in "bit-blasting" SMT solvers (you could
also generate circuits from them but again, performance will likely not
be good).
