What is the difference between these two,
=MATCH(1E+300,A:A)
vs
=MATCH(9.999999E+307,A:A)
Probably nothing.
Both are likely to find to find the last number in column A, since you
probably do not use such large numbers yourself.
It is true that 9.999999E+307 is closer to the largest number that Excel
allows us to enter. Actually, it is 9.99999999999999E+307.
(The largest computable number is about 1.79769313486232E+308; exactly
(2^1023-2^970)*2.
But 1E+300 is easier to remember, IMHO. It is also fewer characters to
enter; we actually type just 1E300.
