68 CHAPTER 3. LANGUAGE Because this is not very convenient a special function called Ò ØÙÔÐ ÓÒ×Ø is available to construct a tuple of a given length, where each element has the same value. Using this function, the program from above is reduced to: ××Ò´ÒØÙÔÐÓÒ×Ø´½¼¼¸½½µ¸ØÙÔÐµ which is displaed as ØÙÔÐ ÒØÙÔÐÓÒ×Ø´½¼¼¸½½µ If we want to construct a tuple with the same length as a given tuple there are two ways to get an easy solution, The first one is based on Ò ØÙÔÐ ÓÒ×Ø: ××Ò´ÒØÙÔÐÓÒ×Ø´ØÙÔÐÓÐ¸½½µ¸ØÙÔÐÒÛµ which is displayed as ØÙÔÐÒÛ ÒØÙÔÐÓÒ×Ø´ØÙÔÐÓÐ¸½½µ The second one is a bit tricky and uses arithmetic functions: ××Ò´´ØÙÔÐÓÐ ¼µ · ½½¸ØÙÔÐÒÛµ which is displaed as ØÙÔÐÒÛ ´ØÙÔÐÓÐ ¼µ · ½½ Here we get first a tuple of the same length with every element set to zero. Then we add the constant to each element. In the case of tuples with different values we have to use the loop version to assign the values to each position: ××Ò´℄¸ØÙÔÐµ ÓÖ ½ ØÓ ½¼¼ Ý ½ ××Ò´ØÙÔÐ¸℄¸ØÙÔÐµ ÒÓÖ which is displaed as ØÙÔÐ ℄ ÓÖ ½ ØÓ ½¼¼ Ý ½ ØÙÔÐ ØÙÔÐ¸℄ ÒÓÖ In this example we construct a tuple with the square values from ½ ¾ to ½¼¼ ¾ . <strong>HDevelop</strong> / 2000-11-16
3.5. EXPRESSIONS FOR INPUT CONTROL PARAMETERS 69 3.5.5 Simple Arithmetic Operations Table 3.9 shows an overview of the available simple arithmetic operations. All operations are left-associative, except the right-associative unary minus operator. The evaluation usually is done from left to right. However, parentheses can change the order of evaluation and some operators have a higher precedence than others (see chapter 3.5.14). » division multiplication Ú · Ú addition and concatenation of strings ¹ subtraction ¹ negation Table 3.9: Arithmetic operations The arithmetic operations in <strong>HDevelop</strong> match the usual definitions. Expressions can have any number of parentheses. The division operator ( » ) can be applied to ÒØÖ as well as to ÖÐ. The result is of type ÖÐ, if at least one of the operands is of type ÖÐ. If both operands are of type ÒØÖ the division is an integer division. The remaining arithmetic operators (multiplication, addition, subtraction, and negation) can be applied to either ÒØÖ or ÖÐ numbers. If at least one operand is of type ÖÐ, the result will be a ÖÐ number as well. In the following example. Î½ »¿ Î¾ »¿º¼ Î¿ ´»¿µ ¾º¼ Î½ is set to 1, Î¾ to 1.3333333, and Î¿ to 2.0. Simple examples can be found in the program ÖØÑØºÚ. 3.5.6 Bit Operations This section describes the operators for bit processing of numbers. The operands have to be integers. Ð×´¸µ Ö×´¸µ Ò ÓÖ ÜÓÖ ÒÓØ left shift right shift bitwise and bitwise or bitwise xor bitwise complement Table 3.10: Bit operations The result of Ð×´½¸¾µ is a bitwise left shift of ½ that is applied ¾ times. If there is no overflow this is equivalent to a multiplication by ¾ ¾ . The result of Ö×´½¸¾µ is a bitwise HALCON 6.0
