Google's Mathematical Limit

How high can Google count? Very high it turns out, but there is a limit. Using the Google search box as a calculator, Google's ceiling appears to be 2.00135558564^1023, which Google says equals 1.79769313 × 10^308.
How high can Google count? Very high it turns out, but there is a limit. Using the Google search box as a calculator, Google's ceiling appears to be 2.00135558564^1023, which Google says equals 1.79769313 × 10^308.Try 3^1023 and you get the search results page instead of a calculated result. The same holds true for 2^1024.

Increasing the number to 2.001355585641^1023 results in the same total, 1.79769313 × 10^308. So that appears to be where Google stops calculating.

Does that mean anything? Not to me. And probably not to anyone else, apart from a few computer scientists. But knowing that Google has a limit is somehow comforting.
