speculable  exu stream  exu block  compute phase   operation   in the decimal floating point value domain   that produces condition codes and rounds toward positive infinity

native on: none

Unsigned integer to decimal float conversion. Rounding towards positive infinity.



u2fdp(d x) → d r0

operands: like Addf [ff:f]
