`ceiling`

Generic Description

Is the ceil alias that rounds a numeric value up to the next integer boundary. It is documented separately because numeric transforms change ranking, thresholds, and buckets in ways planner tools must not guess.

Simple example:

RETURN ceiling(2.1) AS value

Consumer-Level Explanation

Use it when a query should expose the SQL-style spelling while keeping the same bucket semantics as ceil. Prefer this function when the transformation is a deliberate part of the model or report, and name the derived value in a WITH stage when it will be reused.

More Detailed Explanation

ceiling is scalar math, so it is evaluated per row after graph patterns, procedure output, or map projections have produced values. Keep it close to the query when thresholds, ranking, and derived fields need to be auditable and reproducible.

Advanced Example

This example applies ceiling to a named score component after matching graph data, making the derived metric reviewable before ordering.

MATCH (d:Document)
WITH d, properties(d).prize / 1.5 AS normalized_priority
RETURN d.title AS document,
       ceiling(normalized_priority) AS priority_band
ORDER BY priority_band DESC

Real Use Cases

• distance-from-target scoring
• numeric bucketing and normalization before ORDER BY or aggregation
• making scoring formulas visible to query review and assistant tooling

Real Limitations And Tradeoffs

• invalid numeric inputs produce null-like results rather than a repaired value
• math functions do not fix poor feature scaling; choose transformations intentionally
• nondeterministic functions such as random sampling are not appropriate for persisted decisions
