Adds explicit round-off checking to operations that are sensitive to floating point vs. integer round-off errors.
...
Where applied, it assumes that any floating point number that is an integer to within one part in 10^10 should be replaced with that integer.

(bug 15349) Accept more types of minuses in #expr
...
{{#expr:1 − 2}} and {{#expr:1 − 2}} now work, in the same vein as {{#ifexpr:3 < 4|...}} does. This allows human-formatted template values to work more reliably when fed to #expr. Patch by Doug Strain.

* (bug 13216 ) Add trigonometrical functions sin, cos, tan, asin, acos, atan and exp, ln, abs, floor, trunc, ceil, ^, and the constants pi and e.
...
This should help to avoid complicate templates which simulates these functions for geocoding purposes.

Allow expr parser function to accept exponent input (i.e. 3e8). It seems silly to output in a format that we don't accept as input.

* Strip comments early, before template expansion. This mimics the behaviour in the old parser. Added parser tests demonstrating the regression this fixes. The syntactic effect is fairly elegant, with comments taking effect at source level, as expected. The removeHTMLcomments() and preprocessToDom() passes could be merged at a later date.
...
* No need for comment stripping in Expr.php anymore
* Updated srvus() to roughly account for these changes
* Gave comment handling its own preprocessor tag, and split off comment handling from extensionSubstitution(). This only applies for the non-HTML modes, since in HTML mode, comments are stripped early.
* Strip comments from template argument names (PPFrame::newChild).

* (bug 8773) Make error messages from expr.php localizable
...
** Move error messages to ParserFunctions.i18n.php
** Rename 'expr_...' to 'pfunc_expr_...' to be consistent with other messages which are localizable already
* Add CSS class 'error' to output of error messages

Renormalize invalid utf-8 byte in error message.

Would be better to work with an entire character, but it isn't that big a deal. :)
