[TIMOB-7496] Ti API: UI - numbers displayed as float on Android and integer on iOS

Problem

For consistency and parity, we need to decide how we should display numbers by default in the UI across all platforms. For example, the toString() method has always been necessary on Android when displaying a Number type that is an integer in a Label, to prevent it displaying as a float. iOS, on the other hand, displays it as an integer. We should test all UI modules that are able to display text (for example, AlertDialog, TextField, OptionDialog) with an aim of making them consistent.

Test case

The code below returns these results: * Android displays 324.0 * iOS displays 324 Note that the Ti.API.info() statement confirms that label.text is a Number type on Android and iOS.

var win = Ti.UI.createWindow({
	backgroundColor: 'white',
	fullscreen: false
});

var bigNumber = 324;
var label = Ti.UI.createLabel({
	backgroundColor:'green',
	text: bigNumber,
	textAlign: 'center'
});

win.add(label);
win.open();
Ti.API.info('Label.text is type: '+typeof(label.text));
