Examples of java.math.BigDecimal.scale()

java.math.BigDecimal.scale()
Returns the scale of this {@code BigDecimal}. If zero or positive, the scale is the number of digits to the right of the decimal point. If negative, the unscaled value of the number is multiplied by ten to the power of the negation of the scale. For example, a scale of {@code -3} means the unscaledvalue is multiplied by 1000. @return the scale of this {@code BigDecimal}.
