;; There is a difference between `BigInt` and `BigInteger`. The first is from ;; Clojure and should be better for performace, because less unboxing is ;; necessary. The second is from Java and has more functionality. ;; https://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html (type 123N) ;; => clojure.lang.BigInt (type (bigint 123)) ;; => clojure.lang.BigInt (type (biginteger 123)) ;; => java.math.BigInteger (.modInverse (bigint 123) (bigint 4)) ;; IllegalArgumentException No matching method found: modInverse for class ;; clojure.lang.BigInt (.modInverse (biginteger 123) (biginteger 4)) ;; => 3

; It also works for strings (biginteger "12345") => 12345 ; java.math.BigInteger

;; Take care with ratios the decimal part is removed not rounded (biginteger 5/4) ; 1.25 ;; 1 (biginteger 5/2) ; 2.5 ;; 2
