speculable exu stream exu block compute phase operation in the decimal floating point value domain
native on: none
Double the scalar width of a decimal float.
Decimal floats can be 4-16 byte wide. Although the 4 byte format is a pure interchange format and no floating arithmetic operations are available for them.
widend(d op0, width width0) → d r0
operands: like Widend dd:2d
