BitWiseTrailingOnes / Computation Layer
Count consecutive one bits from the least significant bit until the first zero.
Example bit pattern: 11110111 → 3 trailing ones
Common applications:
- Alignment checking
- Memory boundary analysis
- Data structure padding
- Binary protocol analysis
- Power-of-two boundaries
Note: Count starts from the least significant bit position.

columnThe integer column to count trailing ones. Examples:
- 0x0007 → 3 trailing ones
- 0xFFFF → 16 trailing ones
- 0xFFF0 → 0 trailing ones
Must be an integer type column
AsColumn
nameName 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.
