@@ -3,11 +3,11 @@ Edc is a =dc=-style RPN calculator program, distinct in its use of exact real arithmetic. 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 -a₀ = 11/2, +a(0) = 11/2, -a₁ = 61/11, +a(1)= 61/11, -aₙ = 111 - (1130 - 3000/aₙ₋₂)/aₙ₋₁ +a(n) = 111 - (1130 - 3000/a(n-2))/a(n-1) in Emacs =calc= at precisions 5, 10, 30, 60, 100, 110, 120, 130, and 140. |
