Browsing job advertisements, I saw the following question: Do you understand what it takes to efficiently represent 16,777,217 as a float? [Siemens] I don't understand the question. I know that 16,777,216 = 2 24 is the last integer in the sequence [0, 1, ..., N] that can be represented as a float exactly. How can 16,777,217 be represented as a float "efficiently"? 16,777,216 + 1 ? But that's two floats. Please give a hint.

I don't understand the question. I know that 16,777,216 = 2²⁴ is the last integer in the sequence [0, 1, ..., N] that can be represented as a float exactly. How can 16,777,217 be represented as a float "efficiently"? 16,777,216 + 1? But that's two floats.

Please give a hint.
