Can you solve this pier puzzle?

OK, if you want a math teaser, I know 2 different ways to prove that one point zero bar is mathematically identical to zero point nine bar. I do not know how to express the bar with the current font. Just know that there should be a horizontal bar over the final 0 on the left side of the equals, and another horizontal bar over the final 9 on the right side. Without the bars, here's the equation, 1.0 = 0.9, which is obviously false. But with the bars, it is completely true.
