Produce an enum value to classify binary floating points into normal values, subnormals, infinities and NaNs etc.
The exact list is:
- signaling NaN,
- quiet NaN,
- negative Infinity,
- negative Normal,
- negative Subnormal,
- negative Zero,
- positive Zero,
- positive Subnormal,
- positive Normal,
- positive Infinity
operands: like Addf [ff:f]
| Core | In Slots | Latencies |
|---|---|---|
| Silver | E0 E1 | w:w=3 wv:wv=3 d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
| Gold | E0 E1 E2 E3 | w:w=3 wv:wv=3 d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
