BigInt class - dart:core library

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. [...]
override
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. [...]
override
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. [...]
