If you're trying to display figures as degrees you should just type the
number in the cell and then set a custom format to make that value look like
degrees. Type your value in the cell then click on the cell and press CTRL+1
or click on Format->Cells. Click on the Number tab at the top of the window
and then click on Custom in the list on the left, type the following in the
box at the top on the right-hand side:
#.00 ALT+0176
(hold down the ALT key on your keyboard while typing 0176 on the keyboard's
number pad to get the last part of the expression, when you release ALT you
will see a degrees sign). When you click OK the cell will be formatted with
a degree symbol, you can then use the same custom format to format other
cells and will still be able to use the cell contents in calculations.

creating custom formats.
