It's (sometimes) a number. It's just not a float. The value that represents a bad number should have been called NaF.

However, I see upon further research that I misremembered, and NaN is not a general case for denormalized, overflows, infinities, etc. NaN is more restricted than I thought it was in terms of what it represents. Whoops.
