❓ FAQ
QWhy is 7 / 2 equal to 3.5 rather than 3?
ABecause `/` is true division and always returns a float. For integer division use `//`, and for the remainder use `%`. Python 2's `/` did floor division, but Python 3 changed it to true division.
QWhat happens when the divisor is 0?
AIt raises `ZeroDivisionError: division by zero`, and dividing floats by 0 does the same. Check the divisor before dividing, or catch it with `try`/`except`.
QDoes dividing large integers lose precision?
AYes. Any result that is a float is bounded by float precision; for example `10**30 / 1` yields an approximation. For an exact integer result, use `//`.
