70 CHAPTER 3. LANGUAGE right shift of ½ that is applied ¾ times. For non-negative ½ this is equivalent to a division by ¾ ¾ . For negative ½ the result depends on the used hardware. For Ð× and Ö× the result is undefined if the second operand has a negative value or the value is larger than 32. More examples can be found in the program ØºÚ. 3.5.7 String Operations There are several string operations available to modify, select and combine strings. Furthermore, some operations allow to convert numbers (ÖÐ and ÒØÖ) to strings.

The operator has two parameters: The first one (left of the °) is the number that has to be converted. The second one (right of the °) specifies the conversion. This format string consists of the following four parts Ð×Ð ÛØÔÖ×ÓÒÓÒÚÖ×ÓÒ ÖØÖ× So a conversion might look like ½¿¿¾º ° ³º³ Ð× Zero or more flags, in any order, which modify the meaning of the conversion specification. Flags may consist of the following characters: ¹ The result of the conversion is left justified within the field. · The result of a signed conversion always begins with a sign, · or ¹. ×Ô If the first character of a signed conversion is not a sign, a space character is prefixed to the result. This means that if the space flag and · flag both appear, the space flag is ignored. The value is to be converted to an “alternate form”. For and × conversions, this flag has no effect. For Ó conversion (see below), it increases the precision to force the first digit of the result to be a zero. For Ü or conversion (see below), a nonzero result has ¼Ü or ¼ prefixed to it. For , , , , and conversions, the result <strong>HDevelop</strong> / 2000-11-16
3.5. EXPRESSIONS FOR INPUT CONTROL PARAMETERS 71 always contains a radix character, even if no digits follow the radix character. For and conversions, trailing zeros are not removed from the result, contrary to usual behavior. Ð ÛØ An optional string of decimal digits to specify a minimum field width. For an output field, if the converted value has fewer characters than the field width, it is padded on the left (or right, if the left-adjustment flag, - has been given) to the field width. ÔÖ×ÓÒ The precision specifies the minimum number of digits to appear for the , Ó, Ü, or conversions (the field is padded with leading zeros), the number of digits to appear after the radix character for the e and f conversions, the maximum number of significant digits for the conversion, or the maximum number of characters to be printed from a string in s conversion. The precision takes the form of a period º followed by a decimal digit string. A null digit string is treated as a zero. ÓÒÚÖ×ÓÒ ÖØÖ× A conversion character indicates the type of conversion to be applied: ¸Ó¸Ü¸ The integer argument is printed in signed decimal (), unsigned octal (Ó), or unsigned hexadecimal notation (Ü and ). The Ü conversion uses the numbers and letters ¼½¾¿, andthe conversion uses the numbers and letters ¼½¾¿. The precision component of the argument specifies the minimum number of digits to appear. If the value being converted can be represented in fewer digits than the specified minimum, it is expanded with leading zeroes. The default precision is 1. The result of converting a zero value with a precision of 0 is no characters. The floating-point number argument is printed in decimal notation in the style ¹℄Ö, where the number of digits after the radix character, Ö, isequalto the precision specification. If the precision is omitted from the argument, six digits are output; if the precision is explicitly 0, no radix appears. ¸ The floating-point-number argument is printed in the style ¹℄Ö·, where there is one digit before the radix character, and the number of digits after it is equal to the precision. When the precision is missing, six digits are produced; if the precision is 0, no radix character appears. The conversion character produces a number with introducing the exponent instead of . The exponent always contains at least two digits. However, if the value to be printed requires an exponent greater than two digits, additional exponent digits are printed as necessary. ¸ The floating-point-number argument is printed in style or (or in style in the case of a conversion character), with the precision specifying the number of significant digits. The style used depends on the value converted; style is used only if the exponent resulting from the conversion is less than -h or greater than or equal to the precision. Trailing zeros are removed from the result. A radix character appears only if it is followed by a digit. × The argument is taken to be a string, and characters from the string are printed until the end of the string or the number of characters indicated by the precision specification of the argument is reached. If the precision is omitted from the argument, it is interpreted as infinite and all characters up to the end of the string are printed. Similar to the s conversion specifier, except that the string can contain backslash-escape sequences which are then converted to the characters they represent. HALCON 6.0
