AI Got It Wrong - Largest Number
We asked different AI engines to identify the largest of three numbers. The integer part (before the decimal point) is the same for all three numbers; only the fractional part (after the decimal point) differs.
The three fractional parts are .11, .9, and .099999.
The correct answer is the number ending in .9, yet some AI engines incorrectly identify the number ending in .11 as the largest. When comparing decimal fractions, the magnitude of each digit position must be considered sequentially from left to right, not by evaluating the fractional part as a whole number. This is a fundamental principle of decimal representation.
A possible explanation for this error is that some AI engines have not been adequately trained on decimal number comparisons and their proper mathematical handling.
As a follow-up test, we asked the different AI engines to pronounce the number they identified as largest. The engines that correctly identified the number ending in .9 also correctly pronounced it, as there was only a single digit after the decimal point. Some of the other AI engines made pronunciation errors as well.
When reading decimal numbers, each digit after the decimal point should be read individually. For example, .11 would be pronounced as "point one one" (not "point eleven").
Consider the potential repercussions if incorrect decimal comparisons were applied in scientific and engineering disciplines: calculation errors could lead to significant design flaws, inaccurate measurements, or even catastrophic failures in critical systems where precision is essential.
