Mathematical Operators

The order of operations is the same as in Algebra.


-       unary negative sign

* / %   multiply  divide  modulus
+ -     add or substract


Note:  When you do a math operation on two unlike types,
the smaller type is promoted to the higher type.
For example, if you add a double and an int, the int is 
converted to a double inside the cpu.

Alert: When you divide two ints (or any int types), the result
is stored as an int (i.e. you will lose any decimal part).


Examples:




int a,b,c;
b = 13;
c = 5;
a = b + c;  // a would receive the value 18
a = b / c;  // a would receive the value 2 (decimal part truncated)
a = b % c;  // a would receive the value 3 (the remainder)
