In the earlier course of the proof, we divided the left-hand side of this inequality by b to arrive at the formula identical to ε. Equivalently, we can say that the current form is equal to ε · b. We already have a name for this parameter: s. Further, looking at the formula, we can assert that for any irrational r, the value must be greater than zero because if we multiply r by a positive integer (b) and then subtract another integer (a), we always end up with some fractional part.
