Why don't we accept exponential format for integers? - Mailing list pgsql-hackers

Folks,

Is there any good reason that this works:

postgres=# select ('1e+01'::numeric)::integer
postgres-# ;int4
------  10

But this doesn't?

postgres=# select '1e+01'::Integer
postgres-# ;
ERROR:  invalid input syntax for integer: "1e+01"
LINE 1: select '1e+01'::Integer

... or did we just never implement it?
