In order to make sure the difference between two numbers is positive, we use
abs on their subtraction.
Is there an equivalent function that makes sure the ratio between two numbers is (say) larger than one?
I know I can:
fun(Φ) = Φ < 1 ? 1/Φ : Φ
But the same can be argued for
abs(Δ) = Δ < 0 ? -Δ : Δ
I’m just wondering if I missed something.
