It uses IC-Reals, a set of C routines developed at Imperial College that implement a system for performing exact (not arbitrary-precision) computations with real numbers (Edalat and Heckmann 2002). The distinction is subtle, but has significant consequences: try computing the 100th term of the sequence -$$a_0=\frac{11}{2}$$, +a₀ = 11/2, -$$a_1=\frac{61}{11}$$, +a₁ = 61/11, -$$a_n = 111 - \frac{1130 - \frac{3000}{a_{n - 2}}}{a_{n−1}}$$ +aₙ = 111 - (1130 - 3000/aₙ₋₂)/aₙ₋₁ in Emacs =calc= at precisions 5, 10, 30, 60, 100, 110, 120, 130, and 140. -- cgit v1.2.3
