IsFiniteMask / Boolean Layer

Create boolean mask columns identifying finite values in numeric columns. Similar to numpy isfinite() or R's is.finite(). Returns True for regular numbers and False for infinite values or NaN.

Common applications:

Numerical stability checks
Division operation validation
Exponential computation bounds
Mathematical error detection
Statistical outlier analysis

Example:

Index	Float Column	Is Finite
0	1.5	true
1	Inf	false
2	-3.2	true
3	-Inf	false
4	NaN	false

Table

Mask

[, ...]

List of finite checking operations to perform. Each mask creates a new boolean column. Common scenarios:

Validating mathematical operations
Checking computation results
Preparing data for statistical analysis
Identifying valid numerical ranges

At least one mask must be specified.

Select

column

The column to check for finite values. Applicable to numeric columns. The mask will be a boolean column where:

True indicates regular finite numbers
False indicates infinity, -infinity, or NaN

Essential for validating numerical computations and identifying out-of-bounds results.

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.
