speculable  exu stream  exu block  compute phase   operation   in the decimal floating point value domain   that produces condition codes and rounds to nearest, ties away from zero

native on: Decimal8 Decimal16

Exactly round a decimal float to an integer valued float. Rounds towards nearest away from zero.


integeredfz(d x) → d r0

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
