retation as exponentiation. Integer division with truncation of the result toward zero. For example, 7/4 and -7/-4 are truncated to 1 and -7/4 and 7/-4 are truncated to -1. Used to denote division in mathematical equations where no truncation or rounding is intended. Used to denote division in mathematical equations where no truncation or rounding is intended. (i) The summation of f(i) with i taking all integer values from X up to and including y. X % y Modulus. Remainder of X divided by y, defined only for integers X and y with x >=0 and y>0. Logical operators The following logical operators are defined as follows: X && y Boolean logical "and" of X and y. X I y Boolean logical "or" of X and y. Boolean logical "not" k?y:z If X is TRUE or not equal to 0, evaluates to the value of y; otherwise, evaluates to the value of Z. Rec. ITU-T H.264 (01/2012) Relational operators The following relational operators are defined as follows: Greater than. Greater than or equal to. Less than. Less than or equal to. Equal to. Not equal to. When a relational operator is applied to a syntax element or variable that has been assigned the value "na" (not applicable), the value "na" is treated as a distinct value for the syntax element or variable. The value "na" is considered not to be equal to any other value. Bit-wise operators The following bit-wise operators are defined as follows: Bit-wise "and". When operating on integer arguments, operates on a two's complement representation of the integer value. When operating on a binary argument that contains fewer bits than another argument, the shorter argument is extended by adding more significant bits equal to 0. Bit-wise "or". When operating on integer arguments, operates on a two's complement representation of the integer value. When operating on a binary argument that contains fewer bits than another argument, the shorter argument is extended by adding more significant bits equal to 0. Bit-wise "exclusive or". When operating on integer arguments, operates on a two's complement repre
