BigInt class
An arbitrarily large integer.
- Implements
-
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. [...]
- 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. [...] - sign → int
read-only
- Returns the sign of this big integer. [...]
- hashCode → int
read-only, inherited
- The hash code for this object. [...]
- runtimeType → Type
read-only, inherited
- A representation of the runtime type of the object.
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
inherited
- Invoked when a non-existent method or property is accessed. [...]
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
inherited
- The equality operator. [...]
