For Prints, Alerts, Comments etc use DoubleToString().

Floating-point has an infinite number of decimals, it's you, not understanding floating-point and that some numbers can't be represented exactly. (like 1/10.s)
          Double-precision floating-point format - Wikipedia

If you want to see the correct number of digits, convert it to a string with the correct/wanted accuracy.
