javascript-ui-math
Use JavaScript number math safely for front-end UI behavior, including expressions, precedence, coercion, NaN, Infinity, floating-point precision, BigInt limits, modulo wrapping, rounding, random values, and repeatable UI randomness. Use when building sliders, carousels, counters, animation values, randomized UI, financial-ish display values, or debugging numeric edge cases in browser JavaScript.

# JavaScript UI Math
Use this skill for numeric browser behavior that needs predictable edge-case handling. It helps avoid common JavaScript traps around coercion, precision, modulo behavior, rounding, randomization, and BigInt.
## Quick Start
1. Read `guidelines.md` to select the smallest relevant file set.
2. Load `references/ui-numbers/rules.md` for implementation decisions.
3. Load `references/ui-numbers/examples.md` when editing code.
4. Use `workflows/debug-ui-number-logic.md` for multi-step derivation or debugging.
