# C# double.ToString() max number of digits and trailing zeros

It *is* okay to use `value.ToString("0.######")`

. However, you should consider another thing: `double`

is not a decimal (base 10) number. You should not rely on the decimal representation of the number to be anything reasonable - plenty of normal decimal base 10 numbers require infinite decimal expansion in base 2.

If you do care about the decimal representation, it *might* be a better idea to use `decimal`

instead - it's also a floating point number, but in base 10.

And in either case, this involves rounding - that might or might not be what you want.
