Generic Initializer

init(_:)

Creates a new value, rounded to the closest possible representation.

Declaration

init<Source>(_ value: Source) where Source : BinaryInteger

Parameters

value

The integer to convert to a floating-point value.

Discussion

If two representable values are equally close, the result is the value with more trailing zeros in its significand bit pattern.
