Dear PHP Users,

I am trying to figure out how to write a script to increase
a number by .1 or decrease a number by .1 but the number needs
to be in the syntax of x.x. For instance the counting of 5.0 to
6.0 would go:


or vise versa for subtract. How could I do this? Any help would
greatly be appreciated.
