I hope this helps . I am trying to make a program where if I input the degree, it converts it into radian and then calculate its Sine, Cosine and Tangent using Taylor's Theory. Note that I am not supposed to invoke the math module. , You are missing a .:
code :
print("{0}{1:.{2}f}".format("sin= ", sinAns(rad), precision))
           # ^

may help you . You can try using DecimalFormat class to format your numbers as you wish :
code :
float number = 12344.12f;

DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator('.');
symbols.setDecimalSeparator(','); // to be sure it is ','

DecimalFormat decimalFormat = new DecimalFormat();
decimalFormat.setDecimalFormatSymbols(symbols);
decimalFormat.setMaximumFractionDigits(2);

String format = decimalFormat.format(number);

System.out.println(format);
12.344,12
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator('.');
symbols.setDecimalSeparator(','); // to be sure it is ','

DecimalFormat decimalFormat = new DecimalFormat("#.###.00");
decimalFormat.setDecimalFormatSymbols(symbols);

String format = decimalFormat.format(number);

Select *
      ,NewString = format(round(Value,2,1),'0.##')
 From @YourTable
Value       NewString

10.530000   10.53
