If a machine can save only 3 significant digits, the float numbers 12300 and 12358.9 are considered equal since they are both saved as 0.123×10⁵ with simple chopping. Now given the number of significant digits on a machine and two float numbers, you are supposed to tell if they are tr...

On the other hand, the number ⅒ can only be approximated with a non-terminating repeating expansion of binary digits:Because the binary string must eventually end due to the finite memory, its tail gets rounded. By default, Python only shows the most significant digits defined in sys.float...
To only show significant digits, you use the letter g as the format specifier in the f-strings. As the icing on the cake, you can apply one of the available styles that come with Matplotlib to make the resulting plot look more appealing: Python plot_waveform.py # ... def plot(file...
