note that addition of new files under docs/source/lang/api and docs/source/lang/cpp which were just copies of files in docs/source/lang/ imply that change history is lost to git.

-Compound Arithmetic Operators (``+=`` , ``-=``, ``*=``, ``/=``)
-===============================================================
-
-These oparators perform a mathematical operation on a variable with
-another constant or variable. These operators are just a convenient
-shorthand::
-
- x += y; // equivalent to the expression x = x + y;
- x -= y; // equivalent to the expression x = x - y;
- x *= y; // equivalent to the expression x = x * y;
- x /= y; // equivalent to the expression x = x / y;
-
-Here is an example::
-
- int x = 2;
- int y = 10;
-
- x += 4; // x now contains 6
- x -= 3; // x now contains 3
- x *= y; // x now contains 30
- x /= 2; // x now contains 15
- x += max(20, 6); // x now contains 35
- x -= sq(5); // x now contains 15
-
-Parameters
-----------
-
-**x**: a numeric variable
-
-**y**: a numeric variable, number constant, or any other expression
-that evaluates to a number (e.g. call to a function that returns a
-number).
