[issue30361] Docs example: converting mixed types to floating point
New submission from Mihai Borobocea: Section 3.1.1 in the Docs states: "operators with mixed type operands convert the integer operand to floating point" https://docs.python.org/3/tutorial/introduction.html But gives an example using the division operator:
3 * 3.75 / 1.5 7.5 7.0 / 2 3.5
In Python 3, division always returns a float, e.g. when all operands are integers:
3 * 3 / 1 9.0 7 / 2 3.5
To illustrate that "operators with mixed type operands convert the integer operand to floating point" the example should not use division. For example:
3 * 3.75 - 1 10.25 7.0 + 2 9.0

Mariatta Wijaya added the comment: Sorry, I don't know whether this was a sprint project or not.] Saw that the original PR has sprint label on it, I merely copied them over to the backport PRs. Thanks. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue30361> _______________________________________
