I'm guessing that '1234.56e2', and that in this context it's
implicitly converted to a floating-point value of 1234.56e2.
Which means that something like sqrt('1234.56e2') could make
sense, particularly if the argument is some user input rather than
a literal. The point of my example sqrt('x') is precisely that it
almost certainly *doesn't* make sense, though it's legal.
