Methods

__init__	Overload:
back(self)	Gets a last weight
divideByGCD(self)	Divides the integer weights by their gcd.
getAlphabetMass(self, i)	Gets an original (double) alphabet mass by index
getMaxRoundingError(self)
getMinRoundingError(self)
getParentMass(self, decomposition)	Returns a parent mass for a given decomposition
getPrecision(self)	Gets precision.
getWeight(self, i)	Gets a scaled integer weight by index
setPrecision(self, precision)	Sets a new precision to scale double values to integer
size(self)	Gets size of a set of weights
swap(self, index1, index2)	Exchanges weight and mass at index1 with weight and mass at index2

back(self) → int

Gets a last weight

divideByGCD(self) → bool

Divides the integer weights by their gcd. The precision is also adjusted

getAlphabetMass(self, i: int) → float

Gets an original (double) alphabet mass by index

getMaxRoundingError(self) → float

getMinRoundingError(self) → float

getParentMass(self, decomposition: List[int]) → float

Returns a parent mass for a given decomposition

getPrecision(self) → float

Gets precision.

getWeight(self, i: int) → int

Gets a scaled integer weight by index

setPrecision(self, precision: float) → None

Sets a new precision to scale double values to integer

size(self) → int

Gets size of a set of weights

swap(self, index1: int, index2: int) → None

Exchanges weight and mass at index1 with weight and mass at index2
