Examples of java.math.BigDecimal.multiply()

java.math.BigDecimal.multiply()
Returns a {@code BigDecimal} whose value is (this ×multiplicand), and whose scale is {@code (this.scale() +multiplicand.scale())}. @param multiplicand value to be multiplied by this {@code BigDecimal}. @return {@code this * multiplicand}
