C# float magically changing value

Question

I have a float holding a very important value, which has to be VERY exact.
The problem I have is I\'m changing the value of the float ALWAYS only + and - (No divisi

Answer 1

The problem is that with float some fractional numbers cannot be exactly represented. Consider using the decimal data type if you only use + and -, you shouldn't have that problem, since decimal uses a base 10 internally.
