Help with rounding formula

[Spanz712]

Hi there,
I am in desperate need of some help with a formula that is driving me crazy!
I am creating a rostering tool for my company and we want to do a rounding technique which I am having issues with.
What we are getting is number rounded to 1 decimal. We want to round that number to its nearest '.5'.
The rules are:
1. Range is .0 to .29 - the number is rounded down to .0
I.E. 4.15 would be 4
2. Range is 0.3 to .69 - the number is either rounded up or down to .5
I.E. 3.38 and 3.60 would be 3.5
3. Range is .7 and .99 - the number is rounded up to .0
I.E. 5.80 would be 6

Is this possible to do in one formula??? If not, what else could I do??
Thanks!
Hannah

Glad I could help. Someone may have a better, cleaner formula. In the meantime, feel free to use the one I provided (it works).
