R. W. Gosper. Math-Fun list, Apr 9 1998. This constant is the average number of decimal digits necessary to have the equivalent continued fraction representations of a number in base 10. In other words if you have N decimal digits it will give you N/C = N/1.0306 valid partial quotients in average." - _Simon Plouffe_ %D A062542 Steven R.
