In mathematics, the set of positive real numbers, $${\displaystyle \mathbb {R} _{>0}=\left\{x\in \mathbb {R} \mid x>0\right\},}$$ is the subset of those real numbers that are greater than zero. The non-negative real numbers, $${\displaystyle \mathbb {R} _{\geq 0}=\left\{x\in \mathbb {R} \mid x\geq 0\right\},}$$ also … See more The set $${\displaystyle \mathbb {R} _{>0}}$$ is closed under addition, multiplication, and division. It inherits a topology from the real line and, thus, has the structure of a multiplicative topological group or … See more If $${\displaystyle [a,b]\subseteq \mathbb {R} _{>0}}$$ is an interval, then $${\displaystyle \mu ([a,b])=\log(b/a)=\log b-\log a}$$ determines a measure on certain subsets of See more Among the levels of measurement the ratio scale provides the finest detail.
