The following symbols are characters that specify how to combine, compare, or modify the values of an expression. These will be used in performing math operations, setting variables, and comparing operators or variables in conditional statements (ifgoto, ifgosub).

||+ ||addition ||Adds numeric expressions. ||
||-- ||decrement ||Subtracts 1 from the operand. ||
||++ ||increment ||Adds 1 to the operand. ||
||/ ||division ||Divides expression1 by expression2. ||
||++ ||increment ||Adds 1 to an expression. ** Not implemented yet ||
||MOD ||modulo ||Calculates the remainder of expression1 divided by expression2. ||
||* ||multiplication ||Multiplies two numerical expressions. ||
||- ||subtraction ||Used for negating or subtracting. ||
|| << ||left shift ||Shifts the first operand by the given number of bits to the left. ||
|| >> ||right shift ||Shifts the first operand by the given number of bits to the right. ||




'''Comparison'''
||<tablewidth="796px" tableheight="123px"#cccccc>'''Symbol ''' ||<#cccccc>'''Name''' ||<#cccccc>'''Description ''' ||||<style="text-align:center">                        ||
||&& ||and ||Checks to see if both/all expressions are true. (alternatively: and) ||
||`||` ||or ||Checks to see if either/any expressions are true.(alternatively: or) ||
||== ||equality ||Tests two expressions for equality. ||
||> ||greater than ||Compares two expressions and determines whether expression1 is greater than expression2; if it is, the result is true. ||
||>= ||greater than or equal to ||Compares two expressions and determines whether expression1 is greater than or equal to expression2 (true) or expression1 is less than expression2 (false). ||
||!= ||inequality ||Tests for the exact opposite of the equality (==) operator. (Alternatively: <>)||
||< ||less than ||Compares two expressions and determines whether expression1 is less than expression2; if so, the result is true. ||
||<= ||less than or equal to ||Compares two expressions and determines whether expression1 is less than or equal to expression2; if it is, the result is true. ||
||is ||is ||Evaluates whether an object is compatible with a specific data type. ||
||in ||in ||Evaluates whether the given property is part of a specific object. ||
||| ||bitwise OR ||Returns a 1 in each bit position for which the corresponding bits of either or both operands are 1's. ||
||^ ||bitwise XOR ||Returns a 1 in each bit position for which the corresponding bits of either but not both operands are 1's.||
||& ||bitwise AND ||Returns a 1 in each bit position for which the corresponding bits of both operands are 1's.


'''Assignment'''

||= ||assignment ||Assigns the value of expression2 (the operand on the right) to the variable, array element, or property in expression1. ||
||+= ||Addition assignment ||Adds the value of right operand (expression2) to expression1 and assigns the result. ||
||-= ||Subtraction assignment ||Subtracts the value of right operand (expression2) from expression1 and assigns the result. ||
||*= ||Multiplication assignment ||Multiplies the value of the two expressions and assigns the result. ||
||/= ||Division assignment ||Divides the value of the first expression by that of the second and assigns the result. ||


'''String'''
||<tablewidth="796px" tableheight="53px"#cccccc>'''Symbol ''' ||<#cccccc>'''Name''' ||<#cccccc>'''Description ''' ||||<style="text-align:center">                        ||
||+ ||concatenation ||Concatenates (combines) strings. ||
||" ||string delimiter ||When used before and after characters, indicates that the characters have a literal value and are considered a string, not a variable, numerical value, or other element. ||




'''Other'''
||<tablewidth="796px" tableheight="53px"#cccccc>'''Symbol ''' ||<#cccccc>'''Name''' ||<#cccccc>'''Description ''' ||||<style="text-align:center">                        ||
||@ ||Silent mode ||When used at the start of a line it suppresses all log-based output from that single line. ||
||! ||Negation/NOT || Negates the following expression. ||
||? ||Conditional/ternary || if the given condition is true, the first value is given, otherwise the second is given. ||




'''Examples:'''

'''Arithmetic'''

{{{
// Math!
myVar=2
echo 10 * myVar

Result:
17:49:02 20
17:49:03 Script stopped
}}}
'''Comparison'''

{{{
// Testing two numbers using comparison
ifgoto (1 != 2) doesnot
echo "They are equal!"
end

label doesnot
echo "They are not equal!"
end

Result:
17:25:54 They are not equal!
17:25:55 Script stopped
}}}
'''Assignment'''

{{{
//Setting a variable called myVar and giving it a value of 1.
myVar=1
echo "My variable is " + myVar

Result:
17:47:31 My variable is 1
17:47:32 Script stopped
}}}
'''String'''

{{{
//Combine two strings together to form a greeting
myVar="Hello"
myVar2=" there!"
echo myVar + myVar2

Result:
17:56:38 Hello there!
17:56:39 Script stopped
}}}

{{{
// let us know if the variable is true using a conditional operator.
var = true
echo "var " + (var == true ? "is" : "is not") + " true"

Result:
11:17:03 var is true
11:17:04 Script stopped
}}}
