# int class

An integer number.

The default implementation of `int` is 64-bit two's complement integers with operations that wrap to that range on overflow.

Note: When compiling to JavaScript, integers are restricted to valus that can be represented exactly by double-precision floating point values. The available integer values include all integers between -2^53 and 2^53, and some integers with larger magnitude. That includes some integers larger than 2^63. The behavior of the operators and methods in the int class therefore sometimes differs between the Dart VM and Dart code compiled to JavaScript. For example, the bitwise operators truncate their operands to 32-bit integers when compiled to JavaScript.

Classes cannot extend, implement, or mix in `int`.

## Constructors

int.fromEnvironment(String name, { int defaultValue })
  Returns the integer value of the given environment declaration `name`. [...]

  factory

## Properties

bitLength → int
  Returns the minimum number of bits required to store this integer. [...]
  read-only
isEven → bool
  Returns true if and only if this integer is even.
  read-only
isOdd → bool
  Returns true if and only if this integer is odd.
  read-only
sign → int
  Returns the sign of this integer. [...]
  read-only
hashCode → int
  The hash code for this object. [...]
  read-only, inherited
isFinite → bool
  True if the number is finite; otherwise, false. [...]
  read-only, inherited
isInfinite → bool
  True if the number is positive infinity or negative infinity; otherwise, false.
  read-only, inherited

## Methods

abs() → int
  Returns the absolute value of this integer. [...]
ceil() → int
  Returns `this`.
ceilToDouble() → double
  Returns `this.toDouble()`.
floor() → int
  Returns `this`.
floorToDouble() → double
  Returns `this.toDouble()`.
gcd(int other) → int
  Returns the greatest common divisor of this integer and `other`. [...]
modInverse(int modulus) → int
  Returns the modular multiplicative inverse of this integer modulo `modulus`. [...]
modPow(int exponent, int modulus) → int
  Returns this integer to the power of `exponent` modulo `modulus`. [...]
round() → int
  Returns `this`.
roundToDouble() → double
  Returns `this.toDouble()`.
toRadixString(int radix) → String
  Converts this to a string representation in the given `radix`. [...]
toSigned(int width) → int
  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`. [...]
toString() → String
  Returns a String-representation of this integer. [...]
toUnsigned(int width) → int
  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`. [...]
truncate() → int
  Returns `this`.
truncateToDouble() → double
  Returns `this.toDouble()`.
clamp(num lowerLimit, num upperLimit) → num
  Returns this num clamped to be in the range `lowerLimit`-`upperLimit`. [...]
  inherited
compareTo(num other) → int
  Compares this to `other`. [...]
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a non-existent method or property is accessed. [...]
  inherited
remainder(num other) → num
  Returns the remainder of the truncating division of `this` by `other`. [...]
  inherited
toDouble() → double
  Return this num as a double. [...]
  inherited
toInt() → int
  Truncates this num to an integer and returns the result as an int.
  inherited
toStringAsExponential([int fractionDigits ]) → String
  Returns an exponential string-representation of `this`. [...]
  inherited
toStringAsFixed(int fractionDigits) → String
  Returns a decimal-point string-representation of `this`. [...]
  inherited
toStringAsPrecision(int precision) → String
  Converts `this` to a double and returns a string representation with exactly `precision` significant digits. [...]
