Sure it does. If one believes that the negation prefix is not a fundamental component of the number being represented, but rather a separate operation, then it's not a stretch to argue that the decimal point is a binary operation and draw similar conclusions about precedence based upon that.

2.5^2 vs. 2.(5^2)
