Operators in Microsoft Dynamics Axapta 2012

It is used to change the value in variables and fields to control the logical program flow

Types of Operators

     In below example variable i is an integer

     Assignmant Operator
     Modify the contents of a variable or field
     
      =       assign the expression on the right of the equal sign to the variable on the left  

     -=      Decrements the variable on the left by the value on the right
               example :   i -= 4;  Decrement i variable by four every time

     --       Decrements the variable on the left by one
               example :  i--;    Decrement i variable by one

    +=      Increments the variable on the left by the value on the right
               example :  i+= 3;   Increment i variable by Three every time

    ++      Increments the variable on the left by one
              example :   i++;    increment i vaariable by one


     Arithmetic Operators
     Mathematical operations on the values in a variable or field

     +         Plus         -    Adds expression1 to expression2

     -          Minus      -    Subtracts expression2 from expression1

     *         Multiply   -    Multiplies expression1 with expression2

     /         Divides      -    Divides expression1 with expression2

  DIV   Integer          -   Performs an integer division of expression1 with expression2.
            Division       
                                  example : i = 80 DIV 13, Return value of   i = 6  ( i.e.  6*13 = 78, Remainder 2)
 MOD  Integer       -   Returns the rest of an integer division of expression1 with expression2
           Remainder     
                                   example :   i = 80 MOD 13, Return value of i = 2  (i.e. 80/13 - remainder is 2)

     ~         Not           -  Unary operator: performs a binary notoperation

    &    Binary And   -  Performs a binary and-operation on expression1 and expression2

    ^     Binary XOr  -  Performs a binary XOR-operation on expression1 and expression2

     |      Binary Or    -  Performs a binary or-operation on expression1 and expression2

   <<   Left Shift     -  Performs expression2 left shift (a multiplication with two) on expression1
                               
                                  example :  i = 3 << 3;      Retuen value of  i=24    (  i.e.    i = 3*2*2*2)

   >>   Right Shift   -  Performs expression2 right shift (a division by two) on expression1
                              
                                 example :   i = 24 >> 2; Retuen value of i=6    ( i.e. i = 24/2/2)

   ?      Ternary      -  Takes three expressions: expression1 ?
         Operator          expression2 : expression3. If expression1 is true,
                                 expression2 is returned otherwise expression3 is returned
      



     Relational Operators
     Evaluate how two values relate to one another and return either True/False according to the result

     ==     equal Returns true if both expressions are equal

     >=     greater than or equal Returns true if expression1 is greater than or equal to expression2

     <=     less than or equal Returns true if expression1 is less than or equal to expression2

     >       greater than Returns true if expression1 is greater than expression2

     <       less than Returns true if expression1 is less than expression2

     !=     not equal Returns true if expression1 differs from (not equal to) expression2

    &&   and Returns true if both expression1 and expression2 are true

     ||       or Returns true if expression1 or expression2 or both are true

     !        Not A unary operator.
              Negates the expression.Returns true if the expression is false, and false if the
              expression is true

   like  
              Like Returns true if expression1 is like expression2.
              This can use * as a wildcard for zero or more characters and ? as wildcard for one character
              Example : 'xyzpqr' like 'xyz*', Retuen value True
                           'xyzpqr' like 'xyz?', Retuen value False
