This splits ieee_floatt into two parts: 1) ieee_float_valuet stores an IEEE 754 floating-point value. It offers no operations that require rounding, and hence, does not require a rounding mode. 2) ieee_floatt extends ieee_float_valuet with a rounding mode, and hence, offers operators that require rounding.
This adds IEEE 754 TiesToAway rounding mode, which rounds away from zero in case of a tie. The rounding mode is added to three distinct implementations: 1. The implementation for constants, in util/ieee_float.h 2. The implementation that creates a bit-level encoding, in src/solvers/floatbv/float_utils.h. 3. The implementation that creates a word-level encoding, in solvers/floatbv/float_bv.cpp.
