I'm trying to use dm colour rules to change the colour of a text monitor
according to the value of a database field of type double. For values of
0.0 or greater this works fine but I can't get it to work with negative
values; it behaves as if the expression is always false.

The rule in the edd report looks like:

                name="test"
                info[0] {
                        chan="$(C)"
                        value="-1.0"
                        connector="use"
                        comparator="less than"
                        clr="1"
                        RISCpad="0"
                }

Should this work ? If not, is there any other way of doing what I want ?
