Numerors.ValueNumerors' abstract value, which computes a sound overapproximation of the floating-point expressions semantic. It is represented as a triplet containing a sound overapproximation of the real semantic along with sound overapproximations for the absolute and relative errors. Those overapproximations also performs a reduced product between the two errors. For more details, one can look at M. Jacquemin's thesis.
