My understanding is that a rational number is one that can be written as a fraction. For example, 5.1, which can be written as 51/10. But Clojure seems to disagree:
~~~ (rational? 51/10) ;=> true (rational? 5.1) ;=> false (?!) ~~~ Is my definition of "rational" incorrect? Also, my understanding is that a decimal number is one that has a decimal point in it, like, for example, 5.1. However: ~~~ (decimal? 5.1) ;=> false (?!) ~~~ And while typing this, I also notice that while `integer?` acts like I'd expect, `float?` does something weird: ~~~ (integer? 5) ;=> true Yes (integer? 5N) ;=> true Yes (integer? 5.1) ;=> false (float? 5.1) ;=> true (float? 5.1M) ;=> false (?!) ~~~ Maybe I'm confusing "floating point number" with "decimal number" here? If so, what's the difference? Thanks! -- You received this message because you are subscribed to the Google Groups "Clojure" group.
