Polls

POLL: SG6 agrees that by “value” of a floating point type we generally mean the sense of value referred to as “Level
2” in Table 3.1 of ISO/IEC 60559 (2020): {-∞…-0} ∪ {+0…+∞} ∪ {NaN}; “Floating point data — an algebraically closed
system” (As opposed to “Extended real numbers” or “Representations of floating point data”)
