vb.net Math.Round drops last 0 in price?

I am using a Math.Round function in my program as follows

Math.Round((ProductWeightByType * 4.18), 2)

This works perfect except for when the last character is already a 0 then it drops that 0 so example $1.70 becomes $1.7

How do i fix this?

>Solution :

you should try using string format, something like this could do what you need:

String.Format("{0:C2}", Math.Round((ProductWeightByType * 4.18), 2))
