My iPhone tells me that the temperature this morning is −0°F. Not 0°, −0°. I’m getting a kick out of inserting the degree sign (°) — it’s so easy to do so. Just go to Edit, Emoji & Symbols. The degree sign is in Punctuation. It looks like this: °. It’s not to be confused with the masculine ordinal indicator (º), which sounds to me like the name of a strange rare bird.
Wikipedia tells me that signed zero, −0 or +0, is used in computing. And then there’s this detail:
Informally, one may use the notation “−0” for a negative value that was rounded to zero. This notation may be useful when a negative sign is significant; for example, when tabulating Celsius temperatures, where a negative sign means below freezing.I’m not sure why the Weather app would want to round up. From what, −.75°F? As if that’ll make it feel warmer?
By the way, It feels like −15°F.
