Multi-vector unsigned integer convert to floating-point
Convert to single-precision from unsigned 32-bit integer, 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.
It has encodings from 2 classes: Two registers and Four registers
