Обсуждение: More stupid questions: prettyprinting of ints??

hello,

the thing i am making is a bookkepping program. This program handles
multiple currencies, each currency is formatted a bit differently on
from the other.

I do store the amounts as int's in the DB...
In another table i have sample format strings that could be used to
format them...

but if there is an inbuild functionality to format currencies, i will
gladly take it....
on the other hand is it possible to make substring operations in
postgres (some examples somewhere)?

What would be the best way to implement this thing?

yeah forgot another thing....
i want also to write a SQL trigger to parse incoming fields for
preprocessing before DB insertion....

in perl i would do a thing like that:

$format = "9999.999.999,99"; #took out of DB...
#inserting a number into the db....
$theval =~ s/\.//g;
if($theval =~/\S+,\d{2}/)
{ $theval =~ s/,//g; $theval *= 100;
} 
#extracting a number from the db....
$f= $#format;
$i= $#theval;
$res = "";
while($i>=0)
{ if($format[$f] neq "9") {   $res = $format[$f].$res     $f--; }#if($format[$f] neq "9") $res = $theval[$i].$res ;
$i--;$f--;
 
}#while($i>=0)

any chance i could this get out of the frontend into the DB? (as sayd
want to write more frontends so the less is in the frontend and the more
in the DB...)
