You are right. What I've meant that you don't want to use double or float because it's not precise, and you don't want to use BigDecimal because it's slower and, even more important, it'll throw an exception if a given number cannot be represented as decimal number. user=> (/ 1M 3) ArithmeticException Non-terminating decimal expansion; no exact representable decimal result. java.math.BigDecimal.divide (BigDecimal.java:1616) So the general suggestion is to stick to integers and rational numbers as long as possible.
