3d text will not display float

I have a simple health script that displays the health to a 3d text object above the enemy but I get the follow error

Cannot convert "float" to "string"

How do I fix this? My code (javascript)

 var EnemyHealth : float = 10f;
 
 function update(){
     GetComponent(TextMesh).text = (EnemyHealth);
 
 
     if(Input.GetMouseButtonDown(0))
     {
         EnemyHealth -= 1;
     }
 
 }
