76 CHAPTER 3. LANGUAGE The difference and the multiplication (square) are successively applied to each element of both vectors. Afterwards ×ÙÑ computes the sum of the squares. Then the square root of the sum is calculated. After that the dot product of Î½ and Î¾ is determined by the formula: Î ½Î¾ ´Î ½ £ Î ¾ µ 3.5.13 Miscellaneous Functions ×ÓÖØ´Øµ sorting in increasing order ×ÓÖØ ÒÜ´Øµ return index instead of values ÒÚÖ×´Øµ reverse the order of the values ÒÙÑÖ´Úµ convert ×ØÖÒ to a number × ÒÙÑÖ´Úµ test if value is a number ÒÚÖÓÒÑÒØ´×µ value of an environment variable ÓÖ´µ ASCII number of a character Ö´µ convert an ASCII number to a character ÓÖ×´×µ ASCII number of a tuple of strings ÖØ´µ convert a tuple of integers into a string Table 3.18: Miscellaneous functions ×ÓÖØ sorts the tuple values in ascending order, that means, that the first value of the resulting tuple is the smallest one. But again: strings must not be mixed up with numbers. ×ÓÖØ ÒÜ sorts the tuple values in ascending order, but in contrast to ×ÓÖØ it returns the index positions (0..) of the sorted values. The function ÒÚÖ× reverses the order of the tuple values. Both ×ÓÖØ and ÒÚÖ× are the identity operation, if the input is empty, if the tuple is of length 1, or if the tuple contains only one value in all positions, e.g., [1,1,...,1]. ÒÙÑÖ converts a ×ØÖÒ to an ÒØÖ or a ÖÐ depending on the representation. For ÒØÖ and ÖÐ it returns the input. × ÒÙÑÖ returns ØÖÙ for numbers and ×ØÖÒ if it represents a number. ÒÚÖÓÒÑÒØ returns the value of an environment variable. Input is the name of the environment variable as a string. ÓÖ gives the ASCII number of a character as an ÒØÖ. Ö converts an ASCII number to a character. ÓÖ× converts a tuple of strings into a tuple of (ASCII) integers. ÖØ converts a tuple of integers into a string. 3.5.14 Operator Precedence Table 3.19 shows the precedence of the operators for control data. Some operations (like functions, , Ø℄, etc.) are left out, because they mark their arguments clearly. <strong>HDevelop</strong> / 2000-11-16

The condition contains a boolean expression. If the condition is true, the body is executed. Otherwise the execution is continued at the first expression or operator call that follows the word Ò. ´ÓÒØÓÒµ ººº Ò HALCON 6.0
