Data Types – Float And Double

/*
  Primitive Data Types
  - float => Floating Point Number
  --- Test Integer Value In Float Variable
  --- We Make Sure Its Float Not Double By Adding Suffix "f" Or "F"
  --- Test With Auto
  --- 7 Decimal Precision

  - double => Double The Float
  --- 15 Decimal Precision
