Symbols:
>
<
==
!=
||
&&
? a:b		 Meaning:
greater than
less than
equivalent (equal) to
not equivalent (equal) to
or
and
prior true? if true a, otherwise b

 
Action Symbols:
+=
 Usage:
a string variable concatenater
(str+="a" same as str=str+"a")
+= a numeric variable adder
(x+=y is the same as x=x+y)
*= a numeric variable multiplier
(x*=y is the same as x=x*y)
/= a numeric variable divider
(x/=y is the same as x=x/y)
<<= a numeric bitwise operator
(x<<=y the same as x=x<<y)
>>= a numeric bitwise operator
(x>>=y the same as x=x>>y)
&= a numeric bitwise operator
(x&=y the same as x=x&y)
^= a numeric bitwise operator
(x^=y the same as x=x^y)
|= a numeric bitwise operator
(x|=y the same as x=x|y)
%= a numeric modulus operator
(x%=y the same as x=x%y -
a modulus is the remainder
of a division of the first variable
by the second)
x++ a numeric variable incrementer
(x++ is the same as x=x+1)
[If used for setting another value
first returns present value of
x, then increments it)
x-- a numeric variable decrementer
(x-- is the same as x=x-1)
[If used for setting another value
first returns present value of
x, then decrements it]
++x a numeric variable incrementer
(first increments the value of
x, then sets variable equal to x)
--x a numeric variable decrementer
(first decrements the value of
x, then sets variable equal to x)
