Simple Vb / Ssis Data Type Questions

I have a some raw data in a string that looks like



'1989'



I need that to become numeric 19.89



if I define a type double for rawAmount



and do this:



rawAmount = CInt(iRest.Substring(41, 4))

Row.amount2 = rawAmount / 100



where row.amount2 is a type double precision float from my script component task output, I get:



19.899999999999999



what output should i use in this data flow component to get 19.89.



thanks.
