Round / Manipulation Layer

Round floating-point numbers to specified decimal places. Similar to pandas' round() or R's round().

Mathematical behavior:

Values > 0.5 round up (3.7 → 4.0)
Values < 0.5 round down (3.2 → 3.0)
0.5 rounds to nearest even (3.5 → 4.0, 2.5 → 2.0)

Common applications:

Financial calculations (2 decimals)
Percentage representations (1 decimal)
Measurement standardization
Report formatting
Display normalization
Data summarization
Statistical rounding
Precision control

Example: With decimals=2, 3.14159 → 3.14, 2.719 → 2.72

column

Floating-point column to round. Common scenarios:

Calculated ratios needing standardization
Raw measurements requiring formatting
Computed metrics for reporting
Precise values for display
Decimal numbers for alignment

Decimals

u32

Number of decimal places to retain. Common settings:

0: Whole numbers (3.7 → 4)
1: Tenths (3.78 → 3.8)
2: Cents/percentages (3.789 → 3.79)
3: Milliseconds (3.7891 → 3.789)
4: High precision (3.78912 → 3.7891)

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.
