It depends what type of mathematician (and what mathematical context).
"Pure" math deals with approximations and confidence levels less often
than does applied math. So in those areas, mathematicians are likely to
have a first thought of Real or Rational numbers. In statistics,
however, I assume every mathematician would read 1.0 as both a number
and a precision.
