WebThere's no built-in way to see the exact decimal value of a floating point number in .NET, although you can do it with a bit of work. (See the bottom of this article for some code to do this.) By default, .NET formats a double to 15 decimal places, and a float to 7. WebMar 5, 2024 · To elaborate, every floating-point value requires between 1 and X significant digits (i.e. all digits that are not leading or trailing zeros) in order to roundtrip the value (that is, in order for double.Parse(value.ToString()) to return exactly value ). This is at most 17 digits for double and at most 9 digits for float.
