shift() CATALOG shift(integer1[,#ofShifts]) ⇒ integer In Bin base mode: Shifts the bits in a binary integer. You can enter integer1 in any number base; it is converted automatically to a signed, 32-bit binary form. If the magnitude of integer1 is too large for this form, a symmetric modulo operation brings it within the range. If #ofShifts is positive, the shift is to the left. If #ofShifts is negative, the shift is to the right. The default is ë 1 (shift right one bit). In a right shift, the rightmost bit is dropped and 0 or 1 is inserted to match the leftmost bit. In a left shift, the leftmost bit is dropped and 0 is inserted as the rightmost bit. For example, in a right shift: shift(0b1111010110000110101) ¸ 0b111101011000011010 shift(256,1) ¸ 0b1000000000 In Hex base mode: shift(0h78E) ¸ shift(0h78E,ë 2) ¸ shift(0h78E,2) ¸ 0h3C7 0h1E3 0h1E38 Important: To enter a binary or hexadecimal number, always use the 0b or 0h prefix (zero, not the letter O). Each bit shifts right. 0b00000000000001111010110000110101 Inserts 0 if leftmost bit is 0, or 1 if leftmost bit is 1. produces: Dropped 0b00000000000000111101011000011010 The result is displayed according to the Base mode. Leading zeros are not shown. shift(list1 [,#ofShifts]) ⇒ list Returns a copy of list1 shifted right or left by #ofShifts elements. Does not alter list1. If #ofShifts is positive, the shift is to the left. If #ofShifts is negative, the shift is to the right. The default is ë 1 (shift right one element). Elements introduced at the beginning or end of list by the shift are set to the symbol "undef". In Dec base mode: shift({1,2,3,4}) ¸ {undef 1 2 3} shift({1,2,3,4},ë 2) ¸ {undef undef 1 2} shift({1,2,3,4},1) ¸ {2 3 4 undef} shift(string1 [,#ofShifts]) ⇒ string shift("abcd") ¸ " abc" Returns a copy of string1 shifted right or left by #ofShifts characters. Does not alter string1. If #ofShifts is positive, the shift is to the left. If #ofShifts is negative, the shift is to the right. The default is ë 1 (shift right one character). shift("abcd",ë 2) ¸ shift("abcd",1) ¸ " ab" "bcd " Characters introduced at the beginning or end of string by the shift are set to a space. 874 Appendix A: Functions and Instructions
