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

native on: Silver

Binary float greater than or equal comparison. When one of the operands is a NaN, a floating point invalid NaR is produced as the result.

related operations: geqfx


geqf(f x, f y) → f r0

operands: like Addf [ff:f]
