In the world of competitive esports, players often discuss kill/death ratios, where higher is better. My friends sometimes call a poor ratio, like 1 kill to 4 deaths, as 'negative', but that's not quite right. Is there another word to describe values between 0.0 and 1.0, vs values larger than 1.0?

$\begingroup$Since you seem to be primarily interested in rational numbers, a good candidate is proper fraction.
$\endgroup$ 4 $\begingroup$It can be called the Unit Interval
$\endgroup$ 0 $\begingroup$In mathematics, the unit interval is the closed interval [0,1], that is, the set of all real numbers that are greater than or equal to 0 and less than or equal to 1. It is often denoted I (capital letter I). In addition to its role in real analysis, the unit interval is used to study homotopy theory in the field of topology.
Your friends aren't wrong for describing a 1kill, 4 deaths score as negative. They are simply using a different metric, kills-deaths, instead of what you're using, kills/deaths. Both are useful in different scenarios and you should aim to go positive with an improper fraction for a kdr.
$\endgroup$ $\begingroup$A simple mathematical way of describing this is by using the log function.
A number between 0 and 1 has a negative log and a number larger than 1 has a positive log...
So "negative log" and "positive log" could be a way of referring to this.
Note that with this notation, your kills/deaths ration becomes $$ \log (\frac{kills}{deaths})=\log(kills)- \log (deaths) $$
$\endgroup$ 5 $\begingroup$I'm not sure that I would use a term from mathematics. You might consider using a term like "subpar", where "par" would be $1:1$, as in "One kill to four deaths is a subpar kill/death ratio."
