Can anybody plz help me to solve this puzzle?

amt=00002280674231
((amt = amt + 0)) # to remove leading zero's

echo $amt

prints -2014293065

but this works fine for numbers less than 2000000000.

Thanks

Use this instead...
$ x=00000000009822837365732994374589558483928287384458
$ echo ${x##+(0)}
9822837365732994374589558483928287384458
$
