speculable  exu stream  exu block  compute phase   operation   in the decimal floating point value domain  

native on: Decimal8 Decimal16

Decimal float reciprocal dividide. i.e. the result is 1/x.

This operation doesn't need rounding since no precision is lost.


rdivd(d x) → d r0

operands: like Addd [dd:d]
