I work for that company as the Ottawa-based National Affairs Correspondent for Canwest News Service. The blog publishing platform used here is called Blogware and it's developed by Tucows Inc. of Toronto, Ontario, Canada. My use of Blogware should not be taken as an endorsement of that company.

Nope, not floating point errors at all. Look at the paper tape when you run the above calculations. For the first, the conversion routine multiples 12,000,000 by 0.000000, probably some limitation on the significant digits for conversion (I have no idea why). If you press = a second time, it puts the 12000000 after the 0.000000, and 12000000/0.00000012000000 = 1.44. The math is correct, there's just something screwy with the input routines.
Same problem with the second calculation. As mentioned by one comment above, if you don't use parentheses, the result is as expected (correct). If you do use the parens, the paper tape shows very weird behavior; the (2^32) somehow becomes (22). Again 10000/(22) = 454.545...
