No need to bite this one off in small chunks. Just need to make sure the triplets processing works at the next level.

I’m just going to add a new If block for millions that looks a lot like the thousands If block. Of course I’ll be using exponents so I don’t have to type all those zeros.

All tests passed. The rest should be easy. I’m going to go a little sparse on the next tests.

I could create a new If block for each triplet, but I already know I’ll be refactoring, so what’s the point. I need to loop through however many triplets are there and process them.

Error: Overflow. I originally passed in a Double so I could do decimals, but never did the decimals. Anyway, it’s the integer division operator (\) that’s causing the problem. When you use a floating point number, like a Double, in an integer division expression, VBA casts it as a Long first. So anything more than 2.4 billion won’t work. Fortunately, MS has a fix.

All tests passed. And that’s it. I could add decimals, I suppose. Or even larger numbers.

The test-first methodology was pretty enjoyable, I have to say. This isn’t especially complicated code, but biting it off in small chunks made things flow nicely.
