Floating Point Literals

In following expression:

 
  if (ticket_price > 7.50)

What's the type of the literal 7.50? One might think that it's float. However, the actual type is double. To force the compiler to store a floating point literal as a float rather than double, you have to append the affix 'f' to it:

 
  if (ticket_price > 7.50f)
