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 use current dynamic rounding mode

native on: Decimal8 Decimal16

Inexactly convert a decimal floating point value to a signed integer, in current rounding mode and normal modulo overflow.


f2sd(d x) → d r0

operands: like Addd [dd:d]
