Initializers

init()

Create an instance initialized to zero.

Declaration

init()
init(_: Double)

Creates a new instance by rounding the given floating-point value toward zero.

other: A floating-point value. When other is rounded toward zero, the result must be within the range Int16.min...Int16.max.

Declaration

init(_ value: Double)
init(_: Float)

Creates a new instance by rounding the given floating-point value toward zero.

other: A floating-point value. When other is rounded toward zero, the result must be within the range Int16.min...Int16.max.

Declaration

init(_ value: Float)
init(_: Float80)

Creates a new instance by rounding the given floating-point value toward zero.

init(bigEndian:)

Creates an integer from its big-endian representation, changing the byte order if necessary.

Declaration

init(bigEndian value: Int16)
init(bitPattern:)

Construct a Int16 having the same memory representation as the UInt16 bitPattern. No range or overflow checking occurs, and the resulting Int16 may not have the same numeric value as bitPattern--it is only guaranteed to use the same pattern of bits.

Declaration

init(bitPattern: UInt16)
init(integerLiteral:)

Create an instance initialized to value.

Declaration

init(integerLiteral value: Int16)

Creates an integer from its little-endian representation, changing the byte order if necessary.

Declaration

init(truncatingBitPattern: Int)

Construct a Int16 having the same bitwise representation as the least significant bits of the provided bit pattern.

No range or overflow checking occurs.
