Conditional Format

[pgarcia]

I'm looking to hi-lit a cell when the number(s) each 5 or increments of 5.
E.G.
4.9
5.1<--- hi-lit
8.9
10.1
11.1
13.5
15.6<--- hi-lit
19.7
20.25
22.3
26.5<--- hi-lit

Aren't you missing 10.1 and 20.25?

Do you want to highlight everytime there is a 5 in the number?

Please explain again.
