digitalmars.D.learn - Completly static Laurent's polynomials
Hello !
Yesterday, I started a project to implement completly static
Laurent's polynomials (i.e. polynomials formed by z^n and z^-n
monomials).
I thought I could represent these polynomials with an immutable
range of Tuple!(numeric_type, int).
I've tried (and failed) to implement the addition here :
https://github.com/matovitch/StaticLaurent
Is my goal achivable ? How would you do it ?
ps : I am a *total beginner* waiting for any advice(s).

Immutable and ranges do not mix very well. Can you include some
information on what the exact problem is?

"matovitch" <camille.brugel laposte.net> I just clone phobos so we could agree about the line numbers : /usr/include/dmd/phobos/std/conv.d(3889): Error: memcpy cannot be interpreted at compile time, because it has no available source code /usr/include/dmd/phobos/std/range.d(4769): called from here: emplace(addr, front(this._ranges_field_0)) /usr/include/dmd/phobos/std/algorithm.d(3495): called from here: this._current.front() /usr/include/dmd/phobos/std/algorithm.d(1435): called from here: this._input.front() /usr/include/dmd/phobos/std/algorithm.d(1435): called from here: __lambda3(this._input.front()) /usr/include/dmd/phobos/std/algorithm.d(1396): called from here: (FilterResult!(__lambda3, Result) __ctmp1601 = FilterResult(Result); , __ctmp1601).this(rs) laurent.d(53): called from here: filter(myCartesianProduct([Tuple(1.00000, 0), Tuple(1.00000, 1)], [Tuple(2.00000, 0), Tuple(0.5, 1)])) laurent.d(51): called from here: map(filter(myCartesianProduct([Tuple(1.00000, 0), Tuple(1.00000, 1)], [Tuple(2.00000, 0), Tuple(0.5, 1)]))) laurent_test.d(19): Error: template instance laurent_test.main.add!(p1, p2) error instantiating
