Trait Implementations§

source§

impl Semantics for DoubleS

source§

const BITS: usize = 64usize

Total number of bits in the in-memory format.
source§

const PRECISION: usize = 53usize

Number of bits in the significand. This includes the integer bit.
source§

const MAX_EXP: ExpInt = 1_023i16

The largest E such that 2E is representable; this matches the definition of IEEE 754.
source§

const MIN_EXP: ExpInt = _

The smallest E such that 2E is a normalized number; this matches the definition of IEEE 754.
source§

const QNAN_BIT: usize = _

The significand bit that marks NaN as quiet.
source§

const QNAN_SIGNIFICAND: u128 = _

The significand bitpattern to mark a NaN as quiet. NOTE: for X87DoubleExtended we need to set two bits instead of 2.
source§

fn from_bits(bits: u128) -> IeeeFloat<Self>

source§

fn to_bits(x: IeeeFloat<Self>) -> u128

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
