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: none

Signed integer to decimal float conversion. Rounding away from zero.



s2fdfz(d x) → d r0

operands: like Addf [ff:f]
