Initializers
Create an instance initialized to zero.
Declaration
init
()
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 UInt.min...UInt.max
.

Convert from Swift's widest unsigned integer type, trapping on overflow.
Declaration

value
:
UInt64
)
Creates an integer from its big-endian representation, changing the byte order if necessary.
Declaration
init
(
bigEndian
value
:
UInt
)
Construct a UInt
having the same memory representation as
the Int
bitPattern
. No range or overflow checking
occurs, and the resulting UInt
may not have the same numeric
value as bitPattern
--it is only guaranteed to use the same
pattern of bits.
Declaration
init

Creates an integer that captures the full value of the given object identifier.

Creates an integer from its little-endian representation, changing the byte order if necessary.
Declaration
init
(
littleEndian
value

UInt
)
Construct a UInt
having the same bitwise representation as
the least significant bits of the provided bit pattern.
No range or overflow checking occurs.
Declaration

Construct a UInt

The hash value.
Axiom: x == y
implies x.hashValue == y.hashValue

An unsigned integer value type.
On 32-bit platforms,
UInt
is the same size asUInt32
, and on 64-bit platforms,UInt
is the same size asUInt64
.
