ASP.NET can't seem to do simple arithmetic

I'm trying to do a REALLY REALLY simple math here using ASP.NET...

My code is as follows :
Response.Write(CDbl(25.76) + CDbl(18.0) - CDbl(43.76))

Essentially, it's supposed to print out the answer for 25.76 + 18.0 - 43.76 = 0

Problem is, it keeps giving me - 7.105427357601E-15

What in the world am I missing? It's simple arithmetic is it not?
Response.Write(CDbl(25.76) + CDbl(18.0) - CDbl(43.76))

Hi, looks like I've solved my own question :P Can't seem to delete it though.

I simply converted the figures to Cdec (decimals) instead of a Ddbl (double).
