| unsigned | Unsigned integer. Can only contain values that are greater than or equal to 0. The unsigned integer usually contains 4 bytes of data. |
| float | Floating-point number. A number with a decimal point . The values 0.0, 1.2,0.00012345, and -10.5 are all examples of floating-point numbers . Floating-point numbers usually contain 4 bytes of data. |
| double | Double-sized floating-point number. Same as a floating-point number, but it usually contains 8 bytes of data. |
