The P3109 interim report release 3 has a number of changes over release 2:

  • Defines signed/unsigned formats
  • Defines Finite/Extended formats (with/without infinities)
  • Definition is by bias, not emax, rationalizing many edge cases with P near 1 or K
  • Renaming SatMax/SatFinite to SatFinite/SatPropagate
  • A means of quantifying approximate implementations ("kappa-approximate")
  • New operations: Hypot, FMA (non-scaled P3109-P3109), FAA (Fused Add Add), [Min|Max]imum[Magnitude][Number], Clamp
  • Formal verification
