realizing  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

native on: Decimal8 Decimal16

Inexactly convert a decimal floating point value to a signed integer, rounding toward even and producing NaRs on overflow.


f2sdxe(d x) → d r0

operands: like Addd [dd:d]
