It's simple that if you want to show a number as exactly as what it looks, we can cast it to decimal and use the default ToString() like this:

var s = ((decimal)yourNumber).ToString();
//if yourNumber = 0.00000000000000000000000006
//just append the M after it:
var s = (0.00000000000000000000000006M).ToString();
