Double to String keeping trailing zero...

Question

I'm having this issue and i cant think for the best solution, i tried converting the double value into a string and Replace() the ',' to '.'. This works good but only when trailing digits are not zero, i need zeros in my string, even if the value is 1234.0. This worked good for the decimal values. Tried to convert the double to decimal but i loose the decimal digits of there are zeros.

[EDIT] Sorry forgot to mention C#.NET

I know I'm missing something. I would be grateful for some suggestions.

Thank you

Answer 1

This would depend on the language. An example in C#

d.ToString("0.00");

Would produce a double with 2 decimal places nomatter the values (zero or otherwise).

Answer 2

If this is in Java, check out the NumberFormat class's setMinimumFractionDigits() method.

Example:

double d1 = 2.5;
double d2 = 5.0;

NumberFormat nf = NumberFormat.getInstance();
nf.setMinimumFractionDigits(2);

String d1s = nf.format(d1);
String d2s = nf.format(d2);

System.out.println("d1s: " + d1s + " and d2s: " + d2s);

produces

d1s: 2.50 and d2s: 5.00

Answer 3

...and in Fortran, you could do something like: :-)

      write(*,110) x
  110 format (F5.3)

(guess we really have to know what language is being used...)
