Functions

uint256ToBN

▸ uint256ToBN(uint256): bigint

Convert Uint256 to bigint Legacy support Export

Parameters

Name	Type	Description
uint256	Uint256	Uint256 value to convert to bigint

Returns

bigint

BigInt representation of the input Uint256

Example

const uint256Value: Uint256 = { low: 1234567890, high: 1 };
const result = uint256.uint256ToBN(uint256Value);
// result = 340282366920938463463374607433002779346n

isUint256

▸ isUint256(bn): boolean

Test BigNumberish is in the range[0, 2**256-1] Legacy support Export

Parameters

Name	Type	Description
bn	BigNumberish	value to test

Returns

boolean

True if the input value is in the range[0, 2**256-1], false otherwise

Example

const result = uint256.isUint256(12345n);
// result = true
const result1 = uint256.isUint256(-1);
// result1 = false

bnToUint256

▸ bnToUint256(bn): Uint256

Convert BigNumberish (string | number | bigint) to Uint256 Legacy support Export

Parameters

Name	Type	Description
bn	BigNumberish	value to convert to Uint256

Returns

Uint256

Uint256 object representing the BigNumberish value

Example

const result = uint256.bnToUint256(1000000000n);
// result = {"low": "0x3b9aca00", "high": "0x0"}
