This library provides functionality for computing bit properties of an unsigned integer
Functions
mostSignificantBit
Returns the index of the most significant bit of the number, where the least significant bit is at index 0 and the most significant bit is at index 255
function mostSignificantBit(uint256 x) internal pure returns (uint8 r);
Parameters
| Name | Type | Description |
|---|---|---|
x | uint256 | the value for which to compute the most significant bit, must be greater than 0 |
Returns
| Name | Type | Description |
|---|---|---|
r | uint8 | the index of the most significant bit |
leastSignificantBit
Returns the index of the least significant bit of the number, where the least significant bit is at index 0 and the most significant bit is at index 255
function leastSignificantBit(uint256 x) internal pure returns (uint8 r);
Parameters
| Name | Type | Description |
|---|---|---|
x | uint256 | the value for which to compute the least significant bit, must be greater than 0 |
Returns
| Name | Type | Description |
|---|---|---|
r | uint8 | the index of the least significant bit |
