How to ORDER BY correctly?
===

I have problem with sort/order by, not working like I need.

    SELECT `proc` FROM `table` ORDER BY `proc` DESC;

Result:

    80.0 proc
    70.0 proc
    60.0 proc
    50.0 proc
    40.0 proc
    200.0 proc
    20.0 proc
    190.0 proc
    180.0 proc
    170.0 proc
    160.0 proc
    150.0 proc
    140.0 proc
    130.0 proc
    120.0 proc
    110.0 proc
    100.0 proc


What I need is:

    200.0 proc
    190.0 proc
    180.0 proc
    170.0 proc
    160.0 proc
    150.0 proc
    140.0 proc
    130.0 proc
    120.0 proc
    110.0 proc
    100.0 proc
    90.0 proc
    80.0 proc
    70.0 proc
    60.0 proc
    50.0 proc
    40.0 proc
    20.0 proc
