It really doesn’t, both values have the same binary representation. See the
Python FAQ at
<https://docs.python.org/3/faq/design.html#why-are-floating-point-calculations-so-inaccurate
<https://docs.python.org/3/faq/design.html#why-are-floating-point-calculations-so-inaccurate>>
or the floating point section of the tutorial at
<https://docs.python.org/3/tutorial/floatingpoint.html#tut-fp-issues
<https://docs.python.org/3/tutorial/floatingpoint.html#tut-fp-issues>> for
more information.
