Scale double number using big decimal. E.g. Scaling 42.26113 with 2 leads to 42.26.
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;
}
}
