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: none

Inexactly convert a decimal floating point value to a signed integer, rounding toward even and normal modulo overflow.

f2sde(d x) → d r0

operands: like Addf [ff:f]
