Not all that hard.
In my MS Computer Science course, All students had to write a compiler for a language that had only integers and rational numbers.
This was before the days of C++, classes, etc.
Not too much of a sweat.

How did you handle the (least common) denominator problem? Or did you simply ignore it, ignoring the risk that it might overflow? How did you present the results - as if they were floats (through a "(float)numerator/(float)denominator" division) using float output format? Did you do anything to detect common denominators, or did 1/3 + 1/3 end up as 6/9?

I don't remember the details because it was such a long time ago but I distinctly remember that I did determine the least common denominator for fractions and ensured that all rational numbers were stored in their reduced form.

While a rational number type has both advantages and disadvantages and we can discuss that forever, it is an undeniable truth that JSON should have had a rational number type, simply because some languages or libraries already support rational numbers and there should exist a portable way for applications using rational numbers to serialize and exchange these with other applications. A rational number that is within the range of a floating point number type can always be "downgraded" to that floating point number type, but the converse is problematic. For example, is the JSON expression [0.67,0.33] an array with the numbers 2/3 and 1/3 ? If not, then what about [0.6666666666666667,0.3333333333333333]? It would have been clear what was meant if we were allowed to write [2/3,1/3].

Retired.
Again.
Third time.
Got to go out back and make sure the grass is growing.
Going to sit in a rocking chair. Maybe after a few months, I will rock.

The problem with retirement is that you never get a day off. 
I'm pretty sure I would not like to live in a world in which I would never be offended.
I am absolutely certain I don't want to live in a world in which you would never be offended.
Freedom doesn't mean the absence of things you don't like.

That is why I went back to work the other 2 times.

Oh sh*t, I'm looking at my first attempt, I have been threatening to retire for the last 3 years but this time I actually changed my contract to working 10 days a month - from home! By the great Ghu I hope it works. I do NOT want to come back to working full time.

I would have done it sooner but I never got around to commenting my codez.

Hi All,
The useful part of the day has come and gone, I'm too tired to do any more today. I have done what I intended to do and a bit more today (and oh joy the air con has died!) so I am now trying to look busy.
Looking to find secondary sources for components. This allows me to have Altium open and a circuit diagram in front of me with a browser open on a suppliers web page.

I didn't know it was a beer - I assumed it was a "Guinness + something" like Black Velvet.
Mind you, I could go a cold Guinness right about now ...

... because a wise master said:
Do or do not. There is no try.
I think he is right and with the old preprocessor my code would now look like this:
do or do not
{
}
this is why you fail (Exception ex)
{
}

The funny thing that my math teacher never saw Star Wars (he was around 60 when the movie came out and over 70 when teaching me) and still used this phrase daily...
