Instance Property

significandBitPattern

The raw encoding of the value’s significand field.

Declaration

var significandBitPattern: UInt64 { get }

Discussion

The significandBitPattern property does not include the leading integral bit of the significand, even for types like Float80 that store it explicitly.
