Custom rounding up

[paulkaye]

I regularly need to perform this manual rounding operation, and would love to find an automated solution:

If the decimal of the number is between .0 and .4, it's rounded up to the next integer. If the decimal of the number is between .5 and .9, it's rounded up to one integer larger than the next integer.

Examples:

1.3 → 2
4.5 → 6
8.9 → 10
11 → 12

A formula would be fine - I could just paste the formula in the adjacent column. Alternatively, I'd be happy to highlight the relevant cells and run a macro on them.

Thanks in advance!
