Math

Math: clamping, interpolation, wrapping, rounding without float noise, smoothing.

Export	What it does
applyHysteresis	Updates an on/off state with hysteresis: on at or above highThreshold, off at or below lowThreshold, unchanged in between.
ceilToStep	Rounds a number up to a multiple of a step, without float noise.
clamp	Restricts a number to an interval.
floorToStep	Rounds a number down to a multiple of a step, without float noise.
hasSignificantChange	Checks whether a value moved enough since the displayed one to be worth a render (a deadband).
interpolateTable	Reads a lookup table with linear interpolation between its points, such as a calibration curve or a tank gauging table.
inverseLerp	Computes where a value sits between two numbers: the inverse of lerp.
isBetween	Checks whether a number lies between two bounds.
isNearlyEqual	Checks whether two numbers are equal within a tolerance, relative for large numbers and absolute near zero.
lerp	Interpolates linearly between two numbers, exact at both ends and extrapolated outside [0, 1].
moveTowards	Moves a value towards a target at a limited rate (a slew-rate limiter), whatever the frame rate: a needle or a rudder that cannot jump.
ratio	Divides a value by a total, without NaN or Infinity.
remap	Maps a value from an input range to an output range, such as a sensor reading to a gauge angle.
roundToFractionDigits	Rounds a number to a number of decimals, half away from zero, with plain arithmetic: the same result as Number(formatDecimal(value, maxFractionDigits)), much faster.
roundToSignificantDigits	Rounds a number to a number of significant digits, whatever its magnitude.
roundToStep	Rounds a number to the nearest multiple of a step, without float noise: roundToStep(0.3, 0.1) is 0.3.
smoothTowards	Moves a value towards a target with exponential smoothing, whatever the frame rate: about 63 % of the distance is covered every timeConstantMs.
wrap	Wraps a number into [min, max[ with an always-positive modulo, like a heading wrapping at 360°.
