Examples of java.math.BigDecimal.subtract()

java.math.BigDecimal.subtract()
Returns a {@code BigDecimal} whose value is {@code (this -subtrahend)}, and whose scale is {@code max(this.scale(),subtrahend.scale())}. @param subtrahend value to be subtracted from this {@code BigDecimal}. @return {@code this - subtrahend}
