Page Summary
-
The
Array.bitCount()method calculates the number of one-bits in the 64-bit two's complement binary representation of each element in the input array. -
It takes an Array as input and returns an Array of the same dimensions.
-
The examples demonstrate how
bitCount()works for various integer values, including positive, negative, and multi-dimensional arrays.
