An arbitrarily large integer.
- Implemented types
Constructors
-
BigInt.from(num value
) -
Allocates a big integer from the provided
valuenumber.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
intwithout 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. [...]

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
exponentmodulomodulus. [...] -
noSuchMethod(
Invocation invocation ) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
pow(
int exponent ) → BigInt -
Returns
thisto the power ofexponent. [...] -
remainder(
BigInt other ) → BigInt -
Returns the remainder of the truncating division of
thisbyother. [...] -
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
widthbits of this integer, extending the highest retained bit to the sign. This is the same as truncating the value to fit inwidthbits using an signed 2-s complement representation. The returned value has the same bit value in all positions higher thanwidth. [...] -
toString(
) → String -
Returns a String-representation of this integer. [...]
override
-
toUnsigned(
int width ) → BigInt -
Returns the least significant
widthbits of this big integer as a non-negative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher thanwidth. [...]
