RoundSigFigs / Manipulation Layer

Round numbers to specified significant figures (digits that carry meaning). Similar to scientific notation rounding.

Mathematical behavior:

First non-zero digit starts counting
Leading zeros don't count
Trailing zeros after decimal may count

Examples with 3 significant figures:

12345 → 12300
0.012345 → 0.0123
1.2345 → 1.23
0.00012345 → 0.000123

Common applications:

Scientific measurements
Experimental results
Instrument readings
Technical specifications
Uncertainty representation
Precision standardization
Measurement accuracy
Data normalization

column

Numeric column to round. Typical uses:

Physical measurements with uncertainty
Calibrated instrument readings
Calculated results requiring precision
Standardized scientific notation
Normalized technical values

Number of significant digits to retain. Common choices:

2: Rough estimates (12345 → 12000)
3: Standard measurements (12345 → 12300)
4: Precise readings (12345 → 12340)
5: High precision (12345 → 12345) Must be at least 1.

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.
