Perform precise mathematical operations (+, -, *, /, %, **) with arbitrary precision. Supports numbers and strings, with configurable rounding (none, floor, ceil, round). No floating-point errors. Ideal for: token calculations, fee computations, threshold checks, percentage calculations.

Write custom JavaScript to transform data any way you need — format numbers, sort arrays, calculate values, merge objects, and more. Define a transform(input) function; the result is available as {{nodeId.result.output}}. Runs in a secure sandbox with ES6+ support.
