 ## Notes
 
--   For accurate results, the input value should be an integer in the range \[`0`, `2^53-1`].
+-   A 64-bit unsigned integer has a range of \[`0`, `2^64-1`].
+-   Passing a number argument is safe and exact for integers within \[`0`, `2^53`]. For values exceeding `2^53`, JavaScript numbers incur precision loss.
