I have come across a precision issue with double in .NET I thought this only applied to floats but now I see that double is a float.
double test = 278.97 - 90.46;
Debug.WriteLine(test) //188.51000000000005
//correct answer is 188.51
What is the correct way to handle this? Round? Lop off the unneeded decimal places?
Use the decimal data type. “The Decimal value type is appropriate for financial calculations requiring large numbers of significant integral and fractional digits and no round-off errors.”
