Hello,

I have a double, and I want to change it to a string, like this:

C#

double value;
string myString = value.toString();

When value is a number with less than 4 digits after the point, it works fine.
For example,
if value is 0, myString will be 0.
if value is 0.01, myString will be 0.01.

But in cases when value has 4 or more digits after the point, myString is created with a floating point (for example, 1E-05).

I want myString to be created in a format of 0.0000000X for any number of digits after the point, and never use the 1E-0X method.
I also want to keep myString as short as possible, for exmaple when the value is 0, i want myString to be 0 (and not 0.000000).

How can I do it?
Thanks

What are you talking about? "value.toString()" cannot even compile...
