In plain words
What is it for?
Use it when adding, changing, or troubleshooting reactive calculations such as sums, averages, clamping, rounding, and numeric projections.
Why use it?
It helps prevent mistakes when writing or debugging code that imports `@vueuse/math`, especially after API or Vue version changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vueuse-math-skilld scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

  • DEPRECATED: and, or, not — v14 deprecated in favor of original names logicAnd, logicOr, logicNot source

  • BREAKING: Requires Vue 3.5+ — v14 moved to Vue 3.5 as minimum version, enabling native useTemplateRef and MaybeRefOrGetter source

  • BREAKING: ESM-only — v13 dropped CommonJS (CJS) support entirely source

  • NEW: useAverage — reactively calculate average from an array or variadic arguments

  • NEW: useSum — reactively calculate sum from an array or variadic arguments

  • NEW: createProjection — create a reusable numeric projector between two numeric domains

  • NEW: createGenericProjection — create a projector with a custom mapping function for arbitrary types

  • NEW: usePrecision — options now include math property for rounding strategy (floor, ceil, round)

  • NEW: useClamp — returns ComputedRef instead of Ref when input is a getter or readonly ref

  • NEW: useMath — provides reactive access to any standard Math method via key name

  • NEW: logicAnd, logicOr, logicNot — variadic reactive boolean logic supporting multiple refs

  • NEW: useMax, useMin — support both array and variadic arguments for reactive comparison

  • NEW: useAbs, useCeil, useFloor, useRound, useTrunc — dedicated reactive wrappers for common Math methods

  • NEW: useProjection — reactive numeric projection from one domain to another

Also changed: tsdown build system v14 · WatchSource<T> types v14 · MaybeRefOrGetter native v12.8

Best Practices

  • Use useClamp with a mutable ref to create a self-validating state. When a mutable ref is passed, it returns a writable computed that automatically clamps any value assigned to it source

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
