| --------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| `%d` | Display an integer |
| `%f` | Display a float. Specify the number of places to round to by adding a decimal and a number, eg `%.2f` would round to two decimal places. |
For number formatting specifiers, the convention is as follows:
`%-a.bX`
`%`: Start of the formatting specifier
`-`: (optional) If included, justify value left in space. Otherwise, justify right in space
`a`: (optional) If included, the size of the field in characters.
`.`: Separator between `a` and `b`. Optional if `b` is not specified
`b`: The number of decimal places to round to
`X`: The type of format to use, and the end of the specifier. Use `d` for integer base 10 (decimal) representation, `f` for fixed point decimal, and `e` for exponential notation
