FMOV (immediate, unpredicated)

Unconditionally broadcast the floating-point immediate into each element of the destination vector. This instruction is unpredicated.

FMOV <Zd>.<T>, #<const>
is equivalent to

FDUP <Zd>.<T>, #<const>

and is always the preferred disassembly.

Assembler Symbols

<Zd>	Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T>

Is the size specifier, encoded in size:

size	<T>
00	RESERVED
01	H
10	S
11	D

<const>

Is a floating-point immediate value expressable as ±n÷16×2^r, where n and r are integers such that 16 ≤ n ≤ 31 and -3 ≤ r ≤ 4, i.e. a normalized binary floating-point encoding with 1 sign bit, 3-bit exponent, and 4-bit fractional part, encoded in the "imm8" field.
