That depends on the formula. My guess is that the actual formula used by the game for beakers and culture must be:
floor( floor( commerce * rate ) * bonus )
And for gold it would be:
floor( celing( commerce * rate ) * bonus )
Almost. These are the formulas when you only have a tax and a science rate (which is actually the case that we're assuming here). If you also have a culture rate then it works in the following way:
Base Science: floor( commerce * rate )
Base Culture: floor( commerce * rate )
Base Gold: (commerce - Base Science - Base Culture)
The actual science/culture/gold is then calculated by
Science = floor (Base Science * bonus)

These aren't the formulas in Requis' analysis though.
Requies analysis of technology research is mostly not about the production of beakers in a city. It considers that and then looks at how the game modifies the amount of beakers produced by all of your cities in your empire into a progress on the research bar. Your total amount of beaker production can be 1000, but the progress on the research bar 1200 per turn. He does give the above research beaker per city formula at the beginning of his thread but does not mention the rounding down after bonusses from buildings are added. There is a rounding down however.

Given these formulae then the binary rates will give you at least a 10% bonus on total tech and gold output and maybe a lot more (around 40%) for some of them.
The difference is really not that big. You can test it by comparing the gold + science at three settings, 100% science, 0% gold, 50% science, 50% gold and 0% science, 100% gold.
For instance, in my present game these numbers result in:
100% science, 0% gold: 1624 research, 76 gold, 1700 total output
50% science, 50% gold: 807 research, 910 gold, 1717 total output
0% science, 100% gold: 13 research, 1733 gold, 1746 total output
You would expect a 1723 total output when there was no rounding at the 50-50 setting. So the rounding leads to a relative loss of 6/1723 = 0.35%
Almost negligible. Now this is a late game save (1652AD) and in the beginning of the game the effect will be a lot bigger.
I did the same calculation at the various other timepoints in the game:
590 AD: 0% loss
860AD: 0.96% loss
1105 AD: 0.60% loss
1275 AD: 0.73% loss
Nothing very dramatic. Still, the binary science rate can be usefull, but it's not a miracle for the rate of technological development.
