This is for reference to record alternatives for representing fractions:
This is the way I would write 16 raised to the ½ power, and that result cubed. I used the "½" HTML entity, which renders as ½:
(16½)3
But in a recent Washington Post article I saw ½ portion displayed as
and wondered how they did that. Obviously I figured it out, but when I express their exponent fraction in HTML it comes out looking like this:
And this doesn't look like the Washington Post version. Part of the problem is that I don't have access to the font they're using (Franklin), so I used Helvetica, which is pretty close. Here's an image of the Washington Post version that I've tried to scale to the same size:
They're using smaller fonts for the exponents, and I can do the same, so here's my version again with smaller exponent fonts:
The right parentheses crowds the exponent to its left, and I think I can fix that with a little spacing:
The problem with the Washington Post version is that some people read it as 16½ because the ½ exponent was not elevated by very much.
HTML has a number of fraction entities: ½ ⅓ ⅔ ¼ ¾ all the way up to ⅞. After that you have to express it in normal characters, e.g., 113/337. This doesn't look half bad as an exponent:
And perhaps parentheses would improve clarity:
The vertical approach would look like this:
We also have access to Latex, which is a better solution for representing math:
