Use this list operation for a deterministic sequence transformation or summary when item equality, numeric ordering, and mutation expectations are explicit.

Values

Required list input.

Calculate successive sums across a numeric list. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Cumulative sums

The resulting cumulative sums returned as a list.

• Results depend on stable ordering, comparison rules, duplicate and missing-value treatment, rotation convention, numeric parsing, and whether nested values are copied or referenced.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Test empty, singleton, duplicate, negative, and heterogeneous inputs, and retain the source list when reversibility matters.

• Cumulative Product Calculator

  Calculate successive products across a numeric list.

• Sort Numbers Tool

  Sort finite numbers in ascending or descending numeric order.

• Cartesian Product

  Build every ordered pair picking one element from each of two lists.
