stabilize const_float_bits_conv This stabilizes `const_float_bits_conv`, and thus fixes https://github.com/rust-lang/rust/issues/72447. With https://github.com/rust-lang/rust/pull/128596 having landed, this is entirely a libs-only question now. ```rust impl f32 { pub const fn to_bits(self) -> u32; pub const fn from_bits(v: u32) -> Self; pub const fn to_be_bytes(self) -> [u8; 4]; pub const fn to_le_bytes(self) -> [u8; 4] pub const fn to_ne_bytes(self) -> [u8; 4]; pub const fn from_be_bytes(bytes: [u8; 4]) -> Self; pub const fn from_le_bytes(bytes: [u8; 4]) -> Self; pub const fn from_ne_bytes(bytes: [u8; 4]) -> Self; } impl f64 { pub const fn to_bits(self) -> u64; pub const fn from_bits(v: u64) -> Self; pub const fn to_be_bytes(self) -> [u8; 8]; pub const fn to_le_bytes(self) -> [u8; 8] pub const fn to_ne_bytes(self) -> [u8; 8]; pub const fn from_be_bytes(bytes: [u8; 8]) -> Self; pub const fn from_le_bytes(bytes: [u8; 8]) -> Self; pub const fn from_ne_bytes(bytes: [u8; 8]) -> Self; } ```` Cc `@rust-lang/wg-const-eval` `@rust-lang/libs-api`
