Examples of java.math.BigDecimal.movePointLeft()

java.math.BigDecimal.movePointLeft()
Returns a {@code BigDecimal} which is equivalent to this onewith the decimal point moved {@code n} places to the left. If{@code n} is non-negative, the call merely adds {@code n} tothe scale. If {@code n} is negative, the call is equivalentto {@code movePointRight(-n)}. The {@code BigDecimal}returned by this call has value (this × 10^-n) and scale {@code max(this.scale()+n,0)}. @param n number of places to move the decimal point to the left. @return a {@code BigDecimal} which is equivalent to this one with the decimal point moved {@code n} places to the left. @throws ArithmeticException if scale overflows.

          // -1 -> 10's digit, -2 -> 100's digit, etc.
          BigDecimal normalized = value.movePointRight(scale);
          // ...round to that digit
          BigDecimal rounded = normalized.setScale(0,mode);
          // ...and shift the result back to the left (multiply by 10**(abs(scale)))
          return new RubyBigDecimal(getRuntime(), rounded.movePointLeft(scale));
        } else {
          return new RubyBigDecimal(getRuntime(), value.setScale(scale, mode));
        }
