Compiling a well-typed expression should produce a term of the corresponding TermType, assuming that the expression is well-formed in the symbolic environment.

At every point $p\in\mathbb C$, the axis-parallel closed squares centered at $p$ with positive half-width form a neighborhood basis. Equivalently, a set is a neighborhood of $p$ exactly when it contains one of these sufficiently small squares.

Construct a canonical polynomial from a coefficient function Fin n → R. The coefficients are stored in an array (index i gives the coefficient of X^i) and then trimmed to remove trailing zeros. -/ def ofFn [Zero R] [BEq R] [LawfulBEq R] {n : ℕ} (f : Fin n → R) : CPolynomial R := ⟨(Raw.mk (Array.ofFn f)).trim, Raw.Trim.isCanonical_trim _⟩ section Div...
