Rounding values for GUI

Hello, This is my crude code for managing a set of values based on certain things that the player might do. Now as you can see from the screenshot my values are within single floating point decimal places from the Time.deltaTime value, is there anyway to round these to the nearest whole number?

var currentHealth = 100;
var maxHealth = 100.00;

var currentMana : float = 100.0;
var maxMana : int = 100;

var currentStamina : float = 100.0;
var maxStamina : int = 100;

var healthBarLength = 0.0;

private var chMotor : CharacterMotor;

function Start()
{
	healthBarLength = Screen.width / 6;
	chMotor = GetComponent(CharacterMotor);
}
function Update()
{
	AdjustCurrentHealth(0);
	AdjustCurrentMana(0);
	
	//Normal Mana regeneration
	
	if(currentMana >= 0)
	{
		currentMana += Time.deltaTime;
	}
	
	if(currentMana >= maxMana)
	{
		currentMana = maxMana;
	}
	
	if(currentMana <= 0)
	{
		currentMana = 0;
	}
	
	if(Input.GetKeyDown("f"))
	{
		AdjustCurrentMana(-20);
	}
	
	var controller : CharacterController = GetComponent(CharacterController);
	
	if(controller.velocity.magnitude > 0 && Input.GetKey(KeyCode.LeftShift))
	{
		currentStamina -= Time.deltaTime;
		chMotor.movement.maxForwardSpeed = 10;
        chMotor.movement.maxSidewaysSpeed = 10;
	}
	
	else
	{
		chMotor.movement.maxForwardSpeed = 6;
        chMotor.movement.maxSidewaysSpeed = 6;
	}
	
	if(controller.velocity.magnitude > 0 && Input.GetKey(KeyCode.LeftShift) && currentStamina == 0)
	{
		chMotor.movement.maxForwardSpeed = 6;
        chMotor.movement.maxSidewaysSpeed = 6;
	}
	
		//Stamina Regeneration
	if(controller.velocity.magnitude == 0 && (currentStamina >= 0))
	{
		currentStamina += Time.deltaTime;
	}
	
	
	if(currentStamina >= maxStamina)
	{
		currentStamina = maxStamina;
	}
}
function OnGUI ()
{
	//Icons for GUI draw
	GUI.Box(new Rect(5, 30, 40, 20), "HP");
	GUI.Box(new Rect(5, 50, 40, 20), "Mana");
	GUI.Box(new Rect(5, 70, 40, 20), "Stam");
	
	//Health / Mana / Stamina Bars
	GUI.Box(new Rect(45, 30, healthBarLength, 20), currentHealth + "/" + maxHealth);
	GUI.Box(new Rect(45, 50, healthBarLength, 20), currentMana + "/" + maxMana);
	GUI.Box(new Rect(45, 70, healthBarLength, 20), currentStamina + "/" + maxStamina);
}

function AdjustCurrentHealth(adj)
{
	currentHealth += adj;
		
	healthBarLength = (Screen.width / 6) * (currentHealth / maxHealth);
}

function AdjustCurrentMana(adj)
{
	currentMana += adj;
}

Just use ToString with a format string

Something like this:

    currentHealth.ToString("0")

or

    currentHealth.ToString("000")
