What do you mean by "double"?
Is it a string containing these forms of number or is it a variable of type double?

Solution 1

Try this:

C#

double d = 12.345678;
Console.WriteLine("{0,8:000000.00}", d);
Console.WriteLine("{0}", d.ToString("000000.00"));

My 5 (assuming "mydouble" in the question is of type "double")!
Cheers

It seems like a good assumption! :laugh:

For some reason it looks like my 5 is not taken by CP...(?).
Will see if this is a temporal issue only (or only on my PC?).

Caching, probably - the rep history shows an upvote at 04:02pm
So it's at the hamsters end!

if mydouble = 15.163179916317993 , then using your solutions retuns {0.8:000.015,16}

OriginalGriff 28-Nov-14 10:43am

Um...no, it doesn't:
000015.16
000015.16

truth, my mistake buuut the result that I am looking for is ´151631.79´. I will change my question .

Make sure you used the comma before the 8 in 0,8:...

Solution 2

I don't know what I was thinking ! Lately I had to do many parsing and conversions stuff that I didn't realize that for this case the solution were simple maths!!

C#

double dconverted=mydouble*10000; 
d.tostring("######.##");
