 Infinite product - Wikipedia, the free encyclopedia
One important result concerning infinite products is that every entire function f ( z) (i.e., every function that is holomorphic over the entire complex plane) can be factored into an infinite product of entire functions each with at most a single zero.
Euler - Wallis' formula for π is a special case of this.
The product is said to converge when the limit exists and is not zero.

 Abstract
Wessells, C.R.; Cochrane, K.; Deere, C.; Wallis, P.; Willmann, R. Product certification and ecolabelling for fisheries sustainability.
Product labels can be mandatory or voluntary and may refer to different kinds of product characteristics or attributes including the product’s composition or contents, product quality or form, as well as environmental or social aspects of the product’s production process or method.
Product certification is commonly a measure mandated by governments, often mutually agreed upon by regional fisheries management organizations, in order to ensure that only legally harvested and reported fish landings can be traded and sold in the domestic or international markets.

 Amazon.com: Books: The Soul of Politics: Beyond "Religious Right" and "Secular Left"
While Wallis is concerned to integrate politics and spirituality, he does so through what seems to be a theologically liberal approach, namely that religion is good in that it contributes "values" to the public square, but has no politics that is inherent in the life of the church itself.
Wallis is sucinct in his critique of both the Left and the Right, showing their significant failrues and incompleteness.
Wallis calls for what he calls a "prophetic politics of personal and social transformation," one that's built on the Judaeo-Christian insight that righteousness requires both individual and social responsibility.

Wallis's Product Formula for Pi When Newton said, “If I have seen a little farther than others it is because I have stood on the shoulders of giants,” one of those giants was John Wallis.
Wallis taught at Cambridge before becoming Savilian Professor of Geometry at Oxford.
Realizing that he could not attack it head on, Wallis looked for similar integrals that he could handle.

They I would say stick with one of the 2 proposals in your original e-mail - I personally prefer (1), because it nicely separates the numerator and denominator - although you may want to change the datatypes of the "numerator" and "denominator" elements to be integer.
