BigInt class Null safety

An arbitrarily large integer value.

Big integers are signed and can have an arbitrary number of significant digits, only limited by memory.

Implemented types

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
hashCode → int
The hash code for this object. [...]
read-only, inherited
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
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
sign → int
Returns the sign of this big integer. [...]
read-only

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. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
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. [...]

Operators

operator %(BigInt other) → BigInt
Euclidean modulo operator. [...]
operator &(BigInt other) → BigInt
Bit-wise and operator. [...]
operator *(BigInt other) → BigInt
Multiplies other by this big integer. [...]
operator +(BigInt other) → BigInt
Adds other to this big integer. [...]
operator -(BigInt other) → BigInt
Subtracts other from this big integer. [...]
operator /(BigInt other) → double
Double division operator. [...]
operator <(BigInt other) → bool
Whether this big integer is numerically smaller than other.
operator <<(int shiftAmount) → BigInt
Shift the bits of this integer to the left by shiftAmount. [...]
operator <=(BigInt other) → bool
Whether other is numerically greater than this big integer.
operator ==(Object other) → bool
The equality operator. [...]
inherited
operator >(BigInt other) → bool
Whether this big integer is numerically greater than other.
operator >=(BigInt other) → bool
Whether other is numerically smaller than this big integer.
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 integer division operator. [...]
