title: list of Swift arithmetic and comparison operator overloads for numbers?
body: <p>Is there a place in the documentation or something I can look up dynamically in Xcode 6 that shows all the defined operator overloads for numbers such as the binary arithmetic and comparison operators?</p>
  
  <blockquote>
    <p>Swift supports the four standard arithmetic operators for all number types:<BR>
    Addition (+)<BR>
    Subtraction (-)<BR>
    Multiplication (*)<BR>
    Division (/)<BR></p>
    
    <p>Swift supports all standard C comparison operators:<BR>
    Equal to (a == b)<BR>
    Not equal to (a != b)<BR>
    Greater than (a > b)<BR>
    Less than (a &lt; b)<BR>
    Greater than or equal to (a >= b)<BR>
    Less than or equal to (a &lt;= b)<BR></p>

  <p>The reason I would like to know is so that I can see when I'll have to use type casting and when I won't because there is a built-in operator overload for two compatible types.</p>
  
  <p>I have a related question on type casting and automatic upscaling, but before I posted it I wanted to make sure I understand the rules Swift defines by default.</p>
