vb.net (.net 1.1) double question

My app receives double values through e.g. 8740

From the calling app, this translates to £87.40

But when I save it in my audit table (and I understand why it does it this way) it is £8740.00.

Is there something in the .net framework to achieve my goal (place a decimal place in the right place and not on the end) or will I need to write a small function?

Thanks
