Show only two digit after decimal

Use DecimalFormat.

DecimalFormat is a concrete subclass of NumberFormat that formats
decimal numbers. It has a variety of features designed to make it
possible to parse and format numbers in any locale, including support
for Western, Arabic, and Indic digits. It also supports different
kinds of numbers, including integers (123), fixed-point numbers
(123.4), scientific notation (1.23E4), percentages (12%), and currency
amounts ($123). All of these can be localized.

Code snippet -

double i2=i/60000;
tv.setText(new DecimalFormat("##.##").format(i2));

Output -

5.81

How to display two digits after decimal point in SQL Server

select cast(your_float_column as decimal(10,2))
from your_table

decimal(10,2) means you can have a decimal number with a maximal total precision of 10 digits. 2 of them after the decimal point and 8 before.

The biggest possible number would be 99999999.99

Need only 2 digits after decimal point

Very simple. Try this

public double UptoTwoDecimalPoints(double num)
{
    var totalCost = Convert.ToDouble(String.Format("{0:0.00}", num));
    return totalCost;
}

Hot to show only two digits after decimal using double

It looks like the double assigned in line

prezzoTotale = String.valueOf(String.format ("%.2f", (calcoloPrezzoTotale())));

contains a comma (,, i.e. 1,2) due to the locale settings. So take care that parsing happens with the same locale.

Class NumberFormat helps you out:

NumberFormat format = NumberFormat.getInstance(Locale.FRANCE);
Number number = format.parse("1,234");
double d = number.doubleValue();

Looking at your code it could be Locale.ITALY as well ;) check the full Locale list here.

p.s.: String.format() uses Locale.getDefault(); as per documentation. Use logcat to check its value, if you are not sure about the system setting or use the alternative method public static String format(Locale l, String format, Object... args) which allows you to specify the Locale.

how to display two digits after decimal point in a calculated column in SQL?

You could use TRUNCATE

TRUNCATE(X,D)

Returns the number X, truncated to D decimal places. If D is 0, the
result has no decimal point or fractional part. D can be negative to
cause D digits left of the decimal point of the value X to become
zero.

Something like this:

select *, 
        TRUNCATE((TotalDeaths/TotalCases)*100,2) as PercentDeath, 
        TRUNCATE((TotalDeaths/population)*100,2) as DeathPercentPopulation
from ( select location, 
              population, 
              sum(newcases) as TotalCases, 
              sum(newdeaths) as TotalDeaths
      from deaths
      where continent is not null
      group by location
     ) as newtable
order by DeathPercentPopulation desc

Or you could use ROUND function.

The ROUND() function in MySQL is used to round a number to a specified
number of decimal places. If no specified number of decimal places is
provided for round off, it rounds off the number to the nearest
integer.

Syntax :

ROUND(X, D) Parameter : This method accepts two parameters in the
syntax, as mentioned above and described below –

X : The number which to be rounded. D : Number of decimal places up to
which the given number is to be rounded. It is optional. If not given
it round off the number to the closest integer. If it is negative,
then the number is rounded to the left side of the decimal point.

select *, 
        ROUND((TotalDeaths/TotalCases)*100,2) as PercentDeath, 
        ROUND((TotalDeaths/population)*100,2) as DeathPercentPopulation
from ( select location, 
              population, 
              sum(newcases) as TotalCases, 
              sum(newdeaths) as TotalDeaths
      from deaths
      where continent is not null
      group by location
     ) as newtable
order by DeathPercentPopulation desc
