# Validate some rounding functions
Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.

math: Print special error for logical operators Until now, something like `math '7 = 2'` would complain about a "missing" operator. Now we print an error about logical operators not being supported and point the user towards `test`. Fixes #6096

math: Add bitwise and/or functions Just as `math "bitand(5,3)"` and `math "bitor(6,2)"`. These cast to long long before doing their thing, so they truncate to an integer, producing weird results with floats. That's to be expected because float representation is *very* different, and performing bitwise operations on floats feels quite useless. Fixes #7281.

math: Add --base option Currently a bit limited, unfortunately printf's `%a` specifier is absolutely unreadable. So we add `hex` and `octal` with `0x` and `0` prefixes respectively, and also take a number but currently only allow 16 and 8. The output is truncated to integer, so scale values other than 0 are invalid and 0 is implied. The docs mention this may change.
