Signed integers

Like unsigned integers, you can use int by itself to choose the best default size, or specify one of these four specific int sizes:

• int8: 8-bit integer (-128 to 127)
• int16: 16-bit integer (-32768 to 32767)
• int32: 32-bit integer (-2147483648 to 2147483647)
• int64: 64-bit integer (-9223372036854775808 to 9223372036854775807)
