java code

import java.math.BigDecimal;
import java.math.BigInteger;
import java.math.RoundingMode;

public final class DecimalScaler {

    private DecimalScaler() {
    }

    public static BigDecimal scaleBigDecimal(double val, int scale) {
	BigDecimal value = new BigDecimal(Double.toString(val));
	value = value.setScale(scale, RoundingMode.HALF_UP);

	return value;
    }

 
    public static BigDecimal scaleBigDecimal(BigDecimal val, int scale) {
	BigDecimal ret = val.setScale(scale, RoundingMode.HALF_UP);
	return ret;
    }
