Amount being sent as float #97

My client site has very complex tax and shipping calculations. So when it takes the Cart total and times it by 100 here on this line.

https://github.com/tubiz/woo-paystack/blob/master/includes/class-wc-gateway-paystack.php#L877

It is sometimes still sending a float value.
I have a feeling that tax is calculated on each product and not the total, but this was a requirement from the client.
Regardless the gateway only accepts integers.

I did a quick change to the code, it is a dirty fix but it seems to be working fine especially considering that values are not rolled up.

$amount = ! is_int( $amount ) ? intval( $amount ) : $amount;

So the final looks like

$order        = wc_get_order( $order_id );
$amount       = $order->get_total() * 100;
$txnref       = $order_id . '_' . time();
$callback_url = WC()->api_request_url( 'WC_Gateway_Paystack' );

$payment_channels = $this->get_gateway_payment_channels( $order );

$amount = ! is_int( $amount ) ? intval( $amount ) : $amount;

$paystack_params = array(
	'amount'       => $amount,
	'email'        => $order->get_billing_email(),
	'currency'     => $order->get_currency(),
	'reference'    => $txnref,
	'callback_url' => $callback_url,
);

Maybe this will help someone else
