* This structure uses a union to store the long bits integer in two different ways:
|
|
* - An array of `__INTL_U16_PARTS__` uint16_t values, allowing for operations on individual 16-bit segments.
|
|
* - An array of `__INTL_U32_PARTS__` uint32_t values, providing a way to work with 32-bit segments.
|
|
*
|
|
* The union allows for flexibility in how the data is accessed and manipulated,
|
|
* depending on the needs of the operations being performed.
