Edited:

I'm using the module Finance Bitcoin Api.

$btc = $data{"amount"};
$btc = substr($btc,0,32);
chomp($btc);
$btc = sprintf('%.8f', $btc);

$call = $api->call('sendfrom', $sender_account, $receiving_address,$bt
+c,6);

The api call above does not work, however if i substitute the variable $btc for hardcoded value it does work fine. I found the same issue in PHP and the problem was passing a string instead of a numerical. Any wisdom? I'm stuck on it.
Thanks.
