 Data properties:   type: R+  rigour: heuristic (agreement-checked)+  rigour details: Checked here against mpmath's independent computation of the same+    constant, which agreed to past the hundredth digit. That is a stronger check than+    recomputing at two precisions, since the two computations share no code, but neither+    one bounds its own error. Display properties:   number-header: $C_2$
