At first I was thrown off by the way you wrote the value. If "point 9 recurring" means the same thing as: the limit of the sequence 0.9, 0.99, 0.999, etc. then I know it equals 1 because that's what I was told. Math in engineering school was like studying hammers. You don't take them apart, and you don't ask why. You just grab one and start hitting things. For five years.
