BigInt class

An arbitrarily large integer.

Implemented types

Comparable<BigInt>

Constructors

BigInt.from(num value) factory: Allocates a big integer from the provided value number.

Properties

bitLength → int read-only: Returns the minimum number of bits required to store this big integer. [...]
hashCode → int read-only, inherited: The hash code for this object. [...]
isEven → bool read-only: Whether this big integer is even.
isNegative → bool read-only: Whether this number is negative.
isOdd → bool read-only: Whether this big integer is odd.
isValidInt → bool read-only: Whether this big integer can be represented as an int without losing precision. [...]
runtimeType → Type read-only, inherited: A representation of the runtime type of the object.
sign → int read-only: Returns the sign of this big integer. [...]

Methods

abs() → BigInt: Returns the absolute value of this integer. [...]
compareTo(BigInt other) → int override: Compares this to other. [...]
gcd(BigInt other) → BigInt: Returns the greatest common divisor of this big integer and other. [...]
modInverse(BigInt modulus) → BigInt: Returns the modular multiplicative inverse of this big integer modulo modulus. [...]
modPow(BigInt exponent, BigInt modulus) → BigInt: Returns this integer to the power of exponent modulo modulus. [...]
noSuchMethod(Invocation invocation) → dynamic inherited: Invoked when a non-existent method or property is accessed. [...]
pow(int exponent) → BigInt: Returns this to the power of exponent. [...]
remainder(BigInt other) → BigInt: Returns the remainder of the truncating division of this by other. [...]
toDouble() → double: Returns this BigInt as a double. [...]
toInt() → int: Returns this BigInt as an int. [...]
toRadixString(int radix) → String: Converts this to a string representation in the given radix. [...]
toSigned(int width) → BigInt: 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 override: Returns a String-representation of this integer. [...]
toUnsigned(int width) → BigInt: Returns the least significant width bits of this big integer as a non-negative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher than width. [...]

Operators

operator %(BigInt other) → BigInt: Euclidean modulo operator. [...]
operator &(BigInt other) → BigInt: Bit-wise and operator. [...]
operator *(BigInt other) → BigInt: Multiplication operator.
operator +(BigInt other) → BigInt: Addition operator.
operator -(BigInt other) → BigInt: Subtraction operator.
operator /(BigInt other) → double: Division operator.
operator <(BigInt other) → bool: Relational less than operator.
operator <<(int shiftAmount) → BigInt: Shift the bits of this integer to the left by shiftAmount. [...]
operator <=(BigInt other) → bool: Relational less than or equal operator.
operator ==(Object other) → bool inherited: The equality operator. [...]
operator >(BigInt other) → bool: Relational greater than operator.
operator >=(BigInt other) → bool: Relational greater than or equal operator.
operator >>(int shiftAmount) → BigInt: Shift the bits of this integer to the right by shiftAmount. [...]
operator ^(BigInt other) → BigInt: Bit-wise exclusive-or operator. [...]
operator unary-() → BigInt: Return the negative value of this integer. [...]
operator |(BigInt other) → BigInt: Bit-wise or operator. [...]
operator ~() → BigInt: The bit-wise negate operator. [...]
operator ~/(BigInt other) → BigInt: Truncating division operator. [...]

Static Properties

one → BigInt read-only
two → BigInt read-only
zero → BigInt read-only

Static Methods

parse(String source, {int? radix}) → BigInt: Parses source as a, possibly signed, integer literal and returns its value. [...]
tryParse(String source, {int? radix}) → BigInt?: Parses source as a, possibly signed, integer literal and returns its value. [...]
