Subject: [ruby-core:49233] [ruby-trunk - Feature #7328] Move ** operator precedence under unary + and -


Issue #7328 has been updated by trans (Thomas Sawyer).


"Thomas: Please check your facts, e.g. http://en.wikipedia.org/wiki/Order_of_operations#Exceptions_to_the_standard"

1) I did not make this issue.
2) If you read #9 you will see that I did check my facts.
3) Some consideration of #11 would at least be nice.

I would like to ask to consider decreasing ** operator precedence just below that of -/+ unary operators. I know that other languages (eg. Python) have ** operator bind tighter than negation, but seeing -1 ** 0.5 give the result -1 and having to type parenthesis (-1) ** 0.5... Even if it's not worth changing, I'd like to hear this rationalized. I've asked about rationalization of this on SO, and nobody seems to know why this precedence is the way it is.
