speculable exu stream exu block compute phase operation in the decimal floating point value domain using excepting overflow behavior that produces condition codes and rounds to nearest, ties toward even adjacent value
Inexactly convert a decimal floating point value to a signed integer, rounding toward even and producing NaRs on 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 |
