Static Methods

adc(BigInt a, BigInt b, BigInt carry) → List<BigInt>

bitlengthInBytes(BigInt value, {bool sign = false}) → int

Minimum number of bytes needed to represent value. Pass sign: true to reserve room for the sign bit (two's-complement encoding) — required for negative values, and also affects positive values whose top bit would otherwise be misread as a sign bit.

combineU256FromU64Parts(List<BigInt> parts, {Endian order = Endian.big}) → BigInt

ctSelectBigInt(BigInt a, BigInt b, bool choice) → BigInt

divmod(BigInt value, int radix) → (BigInt, BigInt)

Divides a BigInt value by a specified radix and returns both the quotient and the remainder.

fromBytes(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

Converts a list of bytes to a BigInt, considering byte order and sign.

fromBytes128(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

fromBytes16(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

fromBytes256(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

fromBytes32(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

fromBytes64(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

fromBytes8(List<int> bytes, {Endian byteOrder = Endian.big, bool sign = false}) → BigInt

inverseMod(BigInt a, BigInt m) → BigInt

Calculates the modular multiplicative inverse of 'a' modulo 'm'.

mac(BigInt a, BigInt b, BigInt c, BigInt carry) → List<BigInt>

max(BigInt a, BigInt b) → BigInt

parse(dynamic number, {bool allowHex = true}) → BigInt

Parses a dynamic value number into a BigInt.

sbb(BigInt a, BigInt b, BigInt borrow) → List<BigInt>

splitU256ToU64Parts(BigInt number, {Endian order = Endian.big}) → List<BigInt>

toBinary(BigInt value, {int zeroPadBitLen = 0}) → String

Converts a BigInt value to a binary string with optional zero padding.

toBinaryBool(BigInt value, {int? bitLength}) → List<bool>

toBytes(BigInt val, {int? length, Endian byteOrder = Endian.big, bool sign = false}) → List<int>

Converts a BigInt to a byte list with the given length and byte order. Pass sign = true to encode negative values as two's complement.

tryParse(dynamic number, {bool allowHex = true}) → BigInt?

Tries to parse a dynamic value number into a BigInt, returning null if parsing fails.

variableNatDecode(List<int> bytes) → (BigInt, int)

variableNatEncode(BigInt val) → List<int>
