function for last non-blank entry in column?

[mp]

Is there a function that would return the value in the last non-blank cell
in a colunm?
example
"a1" = 10,
"a2" = 25,
"a3" = 3,

formula in "a10" would produce 3

then if later "a4" = 1, "a10" would automatically = 1
(in other words it's not Max, nor Min, nor Sum, nor Average etc)

is that clear?
thanks

"a2" = 25,
"a3" = 3,

=LOOKUP(1E100,A1:A3)

Although LOOKUP "requires" that the lookup table be in ascending
order, this use of LOOKUP works by coincidence because 1E100 is
presumably larger than any numeric value in the lookup table.

Note: If 1E100 is not larger enough, you could use 9E307, which is
closer to the maximum number that Excel permits to be entered. The
largerst computable number is (2^1023-2^970)*2.
