    fn payload(&self) -> u64;

Extension trait for floating point values.

Provides methods for accessing the payload of a NaN according to the webassembly spec.

According to the spec, any canonical NaN is also an arithmetic one.

Required Methods

fn payload(&self) -> u64

Returns the payload bits of a NaN value.

fn signif() -> u32

Returns the number of significant digits in a NaN value.

fn infinite() -> Self

Returns positive infinite.

fn canonical_payload() -> u64

Returns the payload of a canonical NaN.

fn arithmetic_nan(payload: u64) -> Self

Returns an arithmetic NaN with the given payload.

fn canonical_nan() -> Self

Returns a canonical NaN.

fn is_arithmetic_nan(&self) -> bool

Checks if a value is an arithmetic NaN.

fn is_canonical_nan(&self) -> bool

Checks if a value is a canonical NaN.
