BitWiseCountZeros / Computation Layer

Count the number of zero bits (unset bits) in each integer value. Similar to popcount(~x) in C++ or bin(x).count('0') in Python.

For n-bit integers: $y_{i} = n - number of 1’s in x_{i}$

Common applications:

Binary data analysis
Hardware diagnostics
Memory allocation monitoring
Sparse data detection
Network packet analysis
Error detection codes

Note: Result depends on the integer type width (8/16/32/64 bits).

column

The integer column to count zero bits. Examples:

0xFF00 (16-bit) → 8 zeros
0x0000 → all bits zero
0xFFFF → no zeros

Must be an integer type column

Name for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
