No, it's really not quirky. A "rational" number is a ratio of two integers. An irrational number is one that cannot be so expressed. The word "ratio" comes from Latin for calculation. The common english usage of "rational" meaning sensible presumably stems from the ancient Greeks view that only rational numbers make sense. But the mathematical definition is really more fundamental. More rational, one might say :)
Oh, I was being sarcastic against the fallacious “argument”. I know what a rational number is; I've been a math student, you know :)
