I was speaking the other way around: floats represent integers, and
integers represent bit strings; if that means integers are a fundamental
type, bit strings are too.  They both seem equally contrived.

Not what I meant.  Squaring (m^2) is a subset of multiplication (m*n
where m == n), just like remainder is a subset of modulus (m % n where
m and n are integers).  Saying "remainder is built into the language,
so integer division should be too" is like saying "squaring is built
into the language, so square root should be too".
