Java Built-in Types (cont.)

• There are two floating point types, both conforming to IEEE 754 rules:
  • float (32 bits)
  • double (64 bits)
  • gradual underflow and generation of infinity on overflow (no exceptions)
  • mixed floating and integer expressions automatically convert integers
• There is one character type:
  • char (16 bits)
  • Always unsigned
  • Represented in the Unicode character encoding
• There is one logical type:
  • boolean (1 bit)
  • One of two values: true or false
  • No implicit conversion to or from boolean
