What is float?
Float (also called floating-point number): A number with a decimal point, stored as a binary floating-point value of type float. Floats are approximate because many decimal fractions cannot be represented exactly in binary, so tiny rounding errors appear in comparisons.
Float: an example
0.1 + 0.2 gives 0.30000000000000004, so use math.isclose(0.1 + 0.2, 0.3) instead of == when comparing.
