speculable exu stream exu block compute phase operation in the decimal floating point value domain using modulo overflow behavior that produces condition codes and rounds toward positive infinity
Exactly convert a decimal floating point value to a unsigned integer, rounding toward positive infinity and normal modulo overflow.
operands: like Addd [dd:d]
| Core | In Slots | Latencies |
|---|---|---|
| Decimal8 | E0 E1 | d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
| Decimal16 | E0 E1 | d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
