You might also consider

   -100*(-3579.127893//100)

:-)

Which avoids the math.ceil but assumes the number is positive (or zero).

PS: Note that this trick doesn't work with most other common languages that I'm 
familiar with, since the round towards zero instead of down to minus infinity, 
but Python has more clean semantics in this regard.
