FRINTN Multi-vector floating-point round to integral value, to nearest with ties to even Round to the nearest integral floating-point value, with ties rounding to an even value, each element of the two or four source vectors, and place the results in the corresponding elements of the two or four destination vectors. This instruction follows SME2 floating-point numerical behaviors corresponding to instructions that place their results in one or more SVE Z vectors. This instruction is unpredicated.
