0b00000000000001111010110000110101
produces:
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},
ë2) ¸
{undef undef 1 2}
shift({1,2,3,4},1)
¸
{2 3 4 undef}
shift( string1 [, #ofShifts ]) ⇒
⇒⇒
⇒ string
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).
Characters introduced at the beginning or end of
string by the shift are set to a space.
shift("abcd") ¸ " abc"
shift("abcd",
ë2) ¸ " ab"
shift("abcd",1)
¸ "bcd "
ShowStat CATALOG
ShowStat
Displays a dialog box containing the last
computed statistics results if they are still valid.
Statistics results are cleared automatically if the
data to compute them has changed.
Use this instruction after a statistics calculation,
such as
LinReg.

For real and complex expression1 , returns
expression1 /abs( expression1 ) when expression1 ƒ 0.
Returns 1 if
expression1 is positive.
Returns ë 1 if
expression1 is negative.
sign(0) returns „1 if the complex format mode is
REAL; otherwise, it returns itself.
sign(0) represents the unit circle in the complex
domain.
For a list or matrix, returns the signs of all the
elements.
sign(ë 3.2) ¸ ë 1.

If complex format mode is REAL:
sign([ë 3,0,3]) ¸ [ë 1 „1 1]
Inserts 0 if leftmost bit is 0,
or 1 if leftmost bit is 1.
Each bit shifts right.
