Int32 class

An immutable 32-bit signed integer, in the range -2^31, 2^31 - 1. Arithmetic operations may overflow in order to maintain this range.

Implemented types

• IntX

Constructors

Int32([int i = 0])

Constructs an Int32 from an int. Only the low 32 bits of the input are used.

Properties

bitLength → int

Returns the minimum number of bits required to store this integer.

no setter, override

hashCode → int

The hash code for this object.

no setter, override

isEven → bool

Returns true if and only if this integer is even.

no setter, override

isMaxValue → bool

Returns true if and only if this integer is the maximum signed value that can be represented within its bit size.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

abs() → Int32

Returns the absolute value of this integer.

override

clamp(Object lowerLimit, Object upperLimit) → Int32

Clamps this integer to be in the range lowerLimit - upperLimit.

override

compareTo(Object other) → int

Compares this object to another object.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

numberOfLeadingZeros() → int

Returns the number of high-order zeros in this integer's bit representation.

override

numberOfTrailingZeros() → int

Returns the number of low-order zeros in this integer's bit representation.

override

remainder(Object other) → Int32

Returns the remainder of the truncating division of this integer by other.

override

shiftRightUnsigned(int n) → Int32

Unsigned right-shift operator.

override

toBytes() → List<int>

Returns a byte-sequence representation of this integer.

override

toDouble() → double

Returns the double representation of this integer.

override

toHexString() → String

Returns a string representing the value of this integer in hexadecimal notation.

override

toInt() → int

Returns the int representation of this integer.

override

toInt32() → Int32

Returns an Int32 representation of this integer.

override

toInt64() → Int64

Returns an Int64 representation of this integer.

override

toRadixString(int radix) → String

Returns a string representing the value of this integer in the given radix.

override

toSigned(int width) → Int32

Returns the least significant width bits of this integer, extending the highest retained bit to the sign. This is the same as truncating the value to fit in width bits using an signed 2-s complement representation. The returned value has the same bit value in all positions higher than width.

override

toString() → String

A string representation of this object.

override

toUnsigned(int width) → Int32

Returns the least significant width bits of this integer as a non-negative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher than width.

override

override

operator <<(int n) → Int32

Left bit-shift operator.

override

operator <=(Object other) → bool

Relational less than or equal to operator.

override

operator ==(Object other) → bool

Returns true if this Int32 has the same numeric value as the given object. The argument may be an int or an IntX.

override

operator >(Object other) → bool
