WebOn most machines today, that is what you’ll see if you enter 0.1 at a Python prompt. You may not, though, because the number of bits used by the hardware to store floating-point values can vary across machines, and Python only prints a decimal approximation to the true decimal value of the binary approximation stored by the machine. WebAt some point, the computer has to end the number somehow, either by chopping it off or rounding to the nearest floating point number. Computers have to do that fairly often, as even fractions like 1 / 10 1/10 1 / 1 0 1, slash, 10 (which is a short 0.1 0.1 0 . 1 0, point, 1 in decimal) end up as infinitely repeating sequences once converted to ...
