AAPL Oct 18 2014 98.57 Put - odd strikes?

Hi, does anyone know why the aapl Oct 18 2014 strikes are all weird with decimals? Need to open a few put spreads to hedge my position going into the event, but not sure what's going on with the strikes.

Ie: AAPL Oct 18 2014 98.57 Put instead of 98 or 99 strikes.

 

1:7 split. Filter out the fractional strikes.

 

ah yes! All of them are in decimals for the Oct 18, i guess it doesnt really matter, thanks.
