$a \cdot (x \cdot x)$ or $(a \cdot x) \cdot x$?

Abstract

Expressions such as $ax^2$, $axy$, or $ax^3$, where $a$ is a constant, are not unfrequent in computing. There are several ways of parenthesizing them (and therefore, choosing the order of evaluation). Depending on the value of $a$, is there a more accurate evaluation order? We discuss this point (with a small digression on spurious underflows and overflows).
