minus-squarefrezik@midwest.sociallinkfedilinkarrow-up0·edit-28 months agoEven float4. You get +/- 0, 0.5, 1, 1.5, 2, 3, Inf, and two values for NaN. Come to think of it, the idea of -NaN tickles me a bit. “It’s not a number, but it’s a negative not a number”.
minus-squarezaphod@feddit.delinkfedilinkarrow-up0·edit-28 months agoI think you got that wrong, you got +Inf, -Inf and two NaNs, but they’re both just NaN. As you wrote signed NaN makes no sense, though technically speaking they still have a sign bit.
