Initializer

init(_:)

Creates a new instance initialized to the given value.

Declaration

init(_ value: CGFloat)

Parameters

value

The value to use for the new instance.

Discussion

The value of value is rounded to a representable value, if necessary. A NaN passed as value results in another NaN, with a signaling NaN value converted to quiet NaN.
