BigInt class

An arbitrarily large integer.

Implements

Constructors

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

Properties

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

Methods

abs() BigInt
Returns the absolute value of this integer. [...]
compareTo(BigInt other) int
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. [...]
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
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. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited

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 >(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. [...]
operator ==(dynamic other) bool
The equality operator. [...]
