Comparing BigDecimals for Equality | by Brian Terczynski | Medium

January 23, 2022 - So when I looked at the actual value of BigDecimal.ZERO in the debugger, it came up as this: Note that one field in particular is different than the above: the scale. It’s 0 in this case, whereas above it’s 1 . Since they’re different, the == operation does not consider them to be equal. Instead, the Javadoc suggests that compareTo be used, because in this case I don’t actually care about the scale used to represent the number; I only care that the operation’s value is zero, regardless of what scale is used to represent it.

BigDecimal equals() vs. compareTo() | Baeldung

May 2, 2024 - In some specific cases, we want to distinguish numbers by their precision; for example, in physics, we tend to treat numbers with different precisions as different. However, we have additional reasons for such behavior in the BigDecimal class. First of all, the representations of the numbers aren’t the same. The scale is stored in a separate field and defines the floating point’s position: public class BigDecimal extends Number implements Comparable<java.math.BigDecimal> { //... private final int scale; //... }
