The only numbers I will ever spell are one and zero, and only when using them as a pronoun, or for emphasis, respectively.
Is there ever a reason to not to use symbols when dealing with numbers? Why would “fourteen whatevers” ever be preferable to “14 whatevers”. It’s just so much easier to read numbers as symbols, not spelled out.
(Caveat, not including multipliers, like “273 billion”).
19 80 four?
I love the fact this proves the point, that even for emphasis (which I think the title of 1984 is fine to use), it’s LESS clear to spell it out.
I am very thankful my company lets me write numbers and not spell it out.
