// The third parameter is the size of the output string in characters
        // size = number of hex characters to output
        // Each byte produces 2 hex characters

        // Test basic conversion (srcIndex is ignored in the implementation)
        byte[] data1 = { 0x00, 0x01, 0x02, 0x03 };
        assertEquals("00", Hexdump.toHexString(data1, 0, 2)); // 2 chars = 1 byte

Also notice that **FastAPI** is smart enough to notice that the path parameter `item_id` is a path parameter and `q` is not, so, it's a query parameter.

## Query parameter type conversion { #query-parameter-type-conversion }

You can also declare `bool` types, and they will be converted:

{* ../../docs_src/query_params/tutorial003_py310.py hl[7] *}

In this case, if you go to:

```

 * the conversion uses their millisecond value to create the target object.
 * For other types, the conversion uses the string representation of the source object.
 * </p>
 * <p>
 * If no pattern is specified, the pattern used for conversion depends on the locale as follows:
