128-bit SVE
Set all 64-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.
256-bit SVE
Set all 64-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.
512-bit SVE
Set all 64-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.

1024-bit SVE
Set all 64-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.
2048-bit SVE
Set all 64-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.
