This balances with NUM_DIV_CEIL
(which is another form of integer division).

Roc does not let floating point calculations result in `Infinity`, `-Infinity`,
or `NaN`. Any operation which would result in one of these
(such as `sqrt` or `/`) will return a `Result`.
(such as `sqrt` or `/`) will panic.
Similarly to how there are different sizes of floating point numbers,
there are also different sizes of integer to choose from:
