## Stuff to do

- Convert the following numbers from standard decimal
to Q6.6 (fixed point —
6 integer and 6 fraction bits)
`3.3`

`5.375`

`-25.25`

- Convert the following numbers from Q3.3 (fixed point —
3 integer and 3 fraction bits) to standard decimal
`010010`

`100010`

`111111`

- Convert the following decimal numbers into IEEE 754 single precision
(Java
`float`

) representation. Express your result in hexadecimal.`0.25`

`7.7`

`-1024.000000000`

*or*you can even start up Processing or NetBeans make a call to`Float.floatToIntBits()`

; however, at least use the course data representation spreadsheet to view the*raw*bits. - Convert the following IEEE 754 single precision numbers,
represented in hexadecimal, into the corresponding
Java
`float`

.`0x80650000`

`0xBF000000`

`0x44400000`
