Trait Implementations§
source§impl<F: Float> Semantics for FallbackExtendedS<F>
impl<F: Float> Semantics for FallbackExtendedS<F>
source§const PRECISION: usize = Fallback<F>::PRECISION
const PRECISION: usize = Fallback<F>::PRECISION
Number of bits in the significand. This includes the integer bit.
source§const MAX_EXP: ExpInt = _
const MAX_EXP: ExpInt = _
The largest E such that 2^E is representable; this matches the
definition of IEEE 754.
source§const MIN_EXP: ExpInt = _
const MIN_EXP: ExpInt = _
The smallest E such that 2^E is a normalized number; this
matches the definition of IEEE 754.
source§const NONFINITE_BEHAVIOR: NonfiniteBehavior = NonfiniteBehavior::IEEE754
const NONFINITE_BEHAVIOR: NonfiniteBehavior = NonfiniteBehavior::IEEE754
How the nonfinite values Inf and NaN are represented.
const IEEE_MAX_EXP: ExpInt = _
const IEEE_MIN_EXP: ExpInt = _
source§const NAN_SIGNIFICAND_BASE: u128 = _
const NAN_SIGNIFICAND_BASE: u128 = _
The base significand bitpattern of NaNs, i.e. the bits that must always
be set in all NaNs, with other significand bits being either used for
payload bits (if
NAN_PAYLOAD_MASK
covers them) or always unset.source§const NAN_PAYLOAD_MASK: u128 = _
const NAN_PAYLOAD_MASK: u128 = _
The significand bitmask for the payload of a NaN (if supported),
including the “quiet bit” (telling QNaNs apart from SNaNs).
source§const QNAN_SIGNIFICAND: u128 = _
const QNAN_SIGNIFICAND: u128 = _
The significand bitpattern to mark a NaN as quiet (if supported). Read more
