cubicMapping
cubicMapping(
relativeAccuracy):IndexMapping
Defined in: packages/distillate/src/ddsketch/mapping.ts:480
A mapping that approximates log2 with a cubic in the float’s significand:
nearly as compact as logMapping. For matching sketches built with it
elsewhere; in V8 it adds slower than the log mapping, Math.log being cheap.
Parameters
Section titled “Parameters”relativeAccuracy
Section titled “relativeAccuracy”number
Relative error bound, in (0, 1).
Returns
Section titled “Returns”Throws
Section titled “Throws”ParamError when relativeAccuracy is outside (0, 1), or
so small that no value is indexable.
