| short | 16-bit signed integer (-32,768 to 32,767) | 9 000, -5 200 |
| int | 32-bit signed integer (-2³¹ to 2³¹-1) | 5 000 000 000, -299 444, 0 |
| long | 32-bit floating-point number | 15000000000L (the suffix L denotes that it is a long literal) |
| float | 32-bit floating-point number | 5.33, -14.44, 3.14159 |
| double | 64-bit floating-point number | 36.6f (the suffix f denotes that it is a double literal) |
