Dear Martin Marques and other kind people out their ,
In mathematics I would have written it something like
A = antilog (3·3234) = 2144
As I can understand, this is a 10 base log, so that what you want is
10^(3.3234)?
Though antilog did not solve my problem the link below helped me to

What kind of encryption are you looking for? MD5 is a one-way hash:
you can't decrypt the hash to get back the original plaintex

I think there are canned solutions for this available in PostGIS ---
have you looked at that?

Hello
all,
I was trying to find
all zip codes within a given zip code or radius.
I have map points
and Latitude and Longitude in my zip table.
I remember
seeing a post or two referencing this but can't see to find
it.
I've tried the
following with no luck:

This is not a mathematical operation, it is a financial issue
that has to conform to rules develo
The antilog of x is 10^x, so all you need to do is used the ^ operator.
If you are doing the antilog for some other base, there is formula to do
that as well, but I'm forgetting it.

Dear Wei Weng ,
Nope
select exp(3.3234) as a2144
Gives me

But the answer expected is some what near to 2144
The log tables show this

For that you have the exponential operator ^.

Dear all ,
In one of our project I require to calculate antilog of (3.3234)
But I could not find any functions in Documentation for the same.
In mathematics I would have written it something like
A = antilog (3·3234) = 2144
Any suggestions or links are most welcome .

Vishal Kashyap.
