  • Is 9.11 bigger than 9.9? Decimals, not version numbers.

    Gemini 2.5 Pro Experimental: No, 9.11 is not greater than 9.9. Here's how to compare them: Look at the whole number part: Both numbers have 9 before the decimal point, so they are equal so far. Look at the tenths place (the first digit after the decimal): 9.11 has a 1 in the tenths place. 9.9 has a 9 in the tenths place.

    Gemini Pro 1.0: No, 9.11 is not greater than 9.9. In fact, 9.11 is less than 9.9.
