The notation means an integer with 9's.

Interestingly, the incrementally largest term (excluding the term ) occurs precisely at positions , and this term consists of ( 9's.

To compute the entries of this expansion the use of high-precision arithmetic is required; in this calculation, 500000-digit precision was used.

The more common way to represent a continued fraction is as follows:

but this is too wide to display for many terms.
