WebSep 9, 2024 · Together they can represent a very larger range of numbers. 1e-6+1e-6 works because we are only adding the number before e. 1e-0+1e-11 does not work because the number after e will remain as 0, meaning the number before e needs to be 1.000....1 which cannot be represented in its fixed range. – hkchengrex Sep 15, 2024 at 17:09
