NaN

Hello Everyone.

Does anyone know how I can check for NaN? I have this function which works well, except for when Votes and TotalVotes are both equal to 0.

Code:

Public Function CalculatePercentage(ByVal Votes As Integer, ByVal TotalVotes As Integer)
  Dim Calculate
  Calculate = Math.Round(Votes / TotalVotes * 100)
  Calculate = Convert.ToInt32(Calculate)
  Return Calculate
End Function

why dont you check the values before performing the divide function.

if (not Votes = 0 and not TotalVotes = 0)
Calculate = Math.Round(Votes / TotalVotes * 100)

Else describe in more detail what is your problem exactly

Good point!! That works!

It pays to do these things when you're not tired and can actually think straight. :)

Thanks for your help! :)

to put code in try catch block is always a good practice.
you can also use that.

thanks......
