-===== Operators ===== 
-The operators +, -, *, /, and ^ are used to perform addition, subtraction, multiplication, division, exponentiation of floating point and integer numbers. Valid operands are numeric constants and/or numeric variables.\\ 
-\\ 
-The operators %, \, &, |, and ~ are used to calculate modulo, integer division, bitwise and, bitwise or, and bitwise negation (not) of integer expressions.  Floating point numbers will be converted to an integer value before calculation.\\ 
-\\ 
-The = operator is used both for assignment to variables, and to test for equality.  The + operator may be used to perform concatenation of any combination of string constants and string variables.  The : operator can separate multiple statements on a single line. The # operator is a shortcut for the [[rem|Rem]] statement, and is interchangeable with it.\\

-^Arithmetic Operators^^^^ 
-^Operator^Name^Example^Comments^ 
-|+|Addition|a + b|add two numeric values.  If one or both values are strings the plus operator will concatenate the strings into a single string.<sup>2</sup>| 
-|-|Subtraction|a - b|subtract two numeric values| 
-|*|Multiplication|a * b| | 
-|/|Division|a / b|Returns a decimal number of times that b goes into a.| 
-|\|Integer Division|a \ b|Returns the number of whole times that b goes into a.| 
-|%|Modulo|a % b|Returns the remainder of the integer division of a and b.| 
-|%%++%%|Increment Prefix|%%++a%%|Increment (add one) the the variable and return the value after the increment. (may be applied ONLY to numeric variables or array elements)  <sup>1</sup>| 
-|%%++%%|Increment Suffix|%%a++%%|Return the value of the variable and then increment the variable by one for the next time it is accessed. (may be applied ONLY to numeric variables or array elements) <sup>1</sup>| 
-|--|Decrement Prefix|--a|Decrement (subtract one) the the variable and return the value after the decrement. (may be applied ONLY to numeric variables or array elements) <sup>1</sup>| 
-|--|Decrrement Suffix|a--|Return the value of the variable and then decrement the variable by one for the next time it is accessed. (may be applied ONLY to numeric variables or array elements) <sup>1</sup>|

-^Comparison Operators^^^^ 
-^Operator^Name^Example^Comments^ 
-|=|Equal|a = b|Returns true of two values are equal| 
-|%%<%%|Less Than|a < b| | 
-|%%>%%|Greater Than|a > b| | 
-|%%<=%%|Less Than or Equal|a %%<=%% b| | 
-|%%>=%%|Greatet Than or Equal|a >= b| | 
-|%%<>%%|Not Equal|a <> b| | 
- 
-\\ 
-^Logical Operators^^^^ 
-^Operator^Name^Example^Comments^ 
-|NOT|Logical Negation|NOT a| | 
-|AND|Logical Conjunction|a AND b| | 
-|OR|Logical Disjunction|a OR b| | 
-|XOR|Logical Exclusive Disjunction|a XOR b| | 
- 
-\\ 
-^Bitwise Operators^^^^ 
-^Operator^Name^Example^Comments^ 
-|%%~%%|Bitwide Negation|~a| | 
-|%%&%%|Bitwise Conjunction|a & b|If one or both values are strings the ampersand operator will concatenate the strings into a single string.<sup>3</sup>| 
-|%%|%%|Bitwise Disjunction|a %%|%% b|Returns the bits of integer a or integer b.| 
- 
-Bitwise operators only work with long integer values (since 1.99.99.19) in the range of −2,147,483,648 to 2,147,483,647.  Any attempt to use a number outside this range will produce, warnings, error, and/or unexpected results. 
-\\ 
-^String Operators^^^^ 
-^Operator^Name^Example^Comments^ 
-|;|Concatenation|a ; b|Always concatenates (converts numbers to strings)<sup>2</sup>| 
-|+|Concatenation|a + b|Appends b to the end of a (If either (or both) a and b are not numbers, see [[IsNumeric|IsNumeric]]). <sup>2</sup>| 
-|&|Concatenation|a & b|Appends b to the end of a (If either (or both) a and b are not numbers, see [[IsNumeric|IsNumeric]]). <sup>3</sup>|
