Brent will probably jump in, but 1E500 is computer notation for
10^{500}.
More generally, xEy (normally the E is capitalised, but lower case e
is acceptable), where x is a decimal number and y is an integer,
denotes x в 10^y - convenient for ASCII script, where neither the
times symbol (в) nor superscripts are readily available.
