Math & numbers

Numeric helpers for formatting, snapping to a step, generating tick lists, and a fast deterministic pseudo random number generator.

Formatting

• formatNumber — locale-aware number formatting with a fixed number of fraction digits.
• formatPercentage — formats 0..1 as a localized percentage.

Stepping & rounding

• clampWithStepPrecision — clamps a normalized value into [min, max] while snapping to a step.
• countDecimals — number of fraction digits in a number's string form.
• generateStepTicks — generates a list of evenly spaced ticks for an axis.
• roundStep — rounds a value to the nearest multiple of a step.

Randomness

• mulberry32 — seeded Mulberry32 PRNG with next, nextBetween and fork.
