-
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

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
modulomodulus
. [...] -
pow(
int exponent) → BigInt -
Returns
this
to the power ofexponent
. [...] -
remainder(
BigInt other) → BigInt -
Returns the remainder of the truncating division of
this
byother
. [...] -
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 inwidth
bits 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. [...]
-
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 thanwidth
. [...] -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
