0.6.2

• Add Polynomial.calculate_horner
• Update CI python version checks: Remove 3.6, 3.7, add 3.8-3.11

0.6.1

(+) Implemented __call__

0.6.0

Implement definite integral (#49)

0.5.2

Performance improvements (#44 and #45)

0.5.1

Version 0.5.1

• Made FrozenPolynomial and ZeroPolynomial hashable.

Version 0.5.0

New things

• Polynomial division with a remainder with divmod(), e.g.

>>> p, r = divmod(Polynomial(1, 2, 3))
>>> p
Polynomial(1, 0)
>>> r
Polynomial(3)

• Floor division support (// and //=) (#24)
• Modulo support (% and %=) (#24)
• ** and pow() support (#32 )
• <<, >>, <<=, >>= support (#31 )
• Method that calculates and returns the n-th derivative of the polynomial (nth_derivative(n))
• Check if a term or a polynomial's terms all exist in another polynomial with in (#27)
• Add FrozenPolynomial which is immutable (#33)

Fixes things

• Fix str() output for terms with degrees with 10 to 19
• Fix #35 - handle degree changes and zero instance operations
• Fix derivative of zero (#17 )
• Fix multiplying by zero (#18 )
• Fix Constant to number casts (#16)
• Fix default monomial value (#15 )
• Fix bug when setting the leading term to zero (#19)
• Fix repr() for Binomial and Trinomial (#38)
• Simplified source code: module polynomial now divided into the following submodules: core, binomial, trinomial
• Optimize addition and multiplication performance (#41)

Again, kudos to @philippeitis for all the hard work!

Version 0.4.1

🎉 KUDOS TO @philippeitis !!! 🍻

New things

• Different repr() output. It now shows the code that can reproduce the object instead of a human-friendly informal representation. The latter remains the output of str() (e.g. Polynomial(1, 2, 3) vs x^2 + 2x + 3)
• Polynomials now support slicing:

p = Polynomial(4,3,2,1,0)
p[:3] == [0, 1, 2]
p[3:] == [3, 4]
p[2:4] = [8, 8]  # now p == Polynomial(4, 8, 8, 1, 0)

• Implemented __neg__, __pos__, __sub__, __rsub__, __isub__, __imul__, __iadd__.

Fixed things

• Fixed crash when performing multiplication
• Fixed inconsistency and optimized performance when adding polynomials together
• Various other code improvements

Remove package submodule

Changes

• Removed polynomials submodule of package polynomial. Now everything is defined in polynomial.

0.3.1

New stuff

• Added coefficient getters and setters by letter name convention ax^n + bx^{n-1} + cx^{n-2} + ... + yx + z. For example:

p = Polynomial(12, 5, 8, 9)
p.a == p.A == 12  # == p[3]
p.b == p.B == 5  # == p[2]
p.c == p.C == 8  # == p[1]
p.d == p.D == 9  # == p[0]

• Now all classes are within the polynomials submodule of the polynomial module.
• Zero-polynomials's degree is now equal to -math.inf instead of -1

Fixed stuff

• Crash related to the fact that the Monomial's degree can only be a natural number

Fix package name

New things

• Fix package name
