Methods

ceilToMultiple(num multiple) → num

Available on num, provided by the NumX extension

Ceil to the nearest multiple.
floorToMultiple(num multiple) → num

Available on num, provided by the NumX extension

Floor to the nearest multiple.
isBetween(num min, num max) → bool

Available on num, provided by the NumX extension

Checks if the number is between min and max inclusively.
lerp(num a, num b) → double

Available on num, provided by the NumX extension

Linear interpolation between a and b where this is t ∈ [0, 1].
normalized(num fromMin, num fromMax, [num toMin = 0.0, num toMax = 1.0]) → double

Available on num, provided by the NumX extension

Normalizes this value from [fromMin, fromMax] into [toMin, toMax].
normalizedClamped(num fromMin, num fromMax, [num toMin = 0.0, num toMax = 1.0]) → double

Available on num, provided by the NumX extension

Same as normalized but clamps the result to [toMin, toMax].
roundTo(int places) → double

Available on num, provided by the NumX extension

Rounds to places decimal places.
roundToMultiple(num multiple) → num

Available on num, provided by the NumX extension

Rounds to the nearest multiple.
safeNormalized(num fromMin, num fromMax, {num toMin = 0.0, num toMax = 1.0, double fallback = 0.0}) → double

Available on num, provided by the NumX extension

Like normalized but returns fallback instead of throwing when source range is zero. Useful in reactive/UI code where division by zero is a transient state rather than a programmer error.
