title: Can a union be initialized in the declaration?
body: <p>For example, say we have a union</p>
  
  <pre><code>typedef union {
  unsigned long U32;
  float f;
  }U_U32_F;
  </code></pre>
  
  <p>When a variable of this union type is declared, is there a way to set an initial value?</p>
  
  <pre><code>U_U32_F u = 0xffffffff;   // Does not work...is there a correct syntax for this?
  </code></pre>
