Usually comparing against floats is not as deterministic as you would expect. And in other dialects you use #equals: instead of #=
But in Pharo there is no #equals: and instead there is a #closeTo:, but #closeTo: has an arbitrary decimal precision, more than enough for commong arithmetic.

in Smalltalk, the division of two integers is a fraction, not a float.
i.e. 1/5 is 1/5.
