speculable exu stream exu block compute phase operation in the binary floating point value domain
native on: Silver
Double the scalar width of a binary float.
Binary floats can be 2-16 byte wide. Although the 2 byte format is a pure interchange format and no floating arithmetic operations are available for them.
widenf(f op0, width width0) → f r0
operands: like Widenf ff:2f
