Core Java: BigDecimal.equals compares scale as well as value, compareTo does not

BigDecimal's equals treats 2.0 and 2.00 as different because it compares both unscaled value and scale, while compareTo correctly treats them as numerically equal.

Code

BigDecimal a = new BigDecimal("2.0");
BigDecimal b = new BigDecimal("2.00");
System.out.println("a.equals(b): " + a.equals(b));
System.out.println("a.compareTo(b) == 0: " + (a.compareTo(b) == 0));

Output

a.equals(b): false
a.compareTo(b) == 0: true
