try using a double instead.

floats, by how they are rapresented, are not good for precision unless we are talking about extremely small numbers.

Here is a nice little article explaining why floats may lose precision (its for cpp, but the general concept should be the same for c#): https://learn.microsoft.com/en-us/cpp/build/why-floating-point-numbers-may-lose-precision?view=msvc-170

Edit: I found this 13 years old question in the suggested section that might definitivelty help you understand more about floats and doubles: Difference between decimal, float and double in .NET?
