While not normally needed, how does one go about utilizing math functions with very large numbers, without getting an "overflow" error? Numbers treated as integers go from -2,147,483,648 to 2,147,483,647; yet, how could one utilize, say, 1e+15 or 3e+50? I’ve tried using CDbl and CLng, neither of which seem to work, at least not with carrying out functions which allow their use. For example, below wanting to convert a trillion to a base 2 number. An "overflow" results on the astrieck line regardless of using CDbl or CLng anywhere. Base = 2 ’ Converts to new base
