realizing  exu stream  exu block  compute phase   operation   in the binary floating point value domain   that produces condition codes and rounds to nearest, ties toward even adjacent value

native on: Silver Gold

Inexactly round a binary float to an integer valued float. Rounds towards nearest even.


integerfe(f x) → f r0

operands: like Addf [ff:f]
