rotate() MATH/Base menu
rotate( integer1 [, #ofRotations ]) ⇒ integer
Rotates 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.
In Bin base mode:
rotate(0b1111010110000110101)
¸
0b10000000000000111101011000011010
rotate(256,1) ¸ 0b1000000000
If #of Rotations is positive, the rotation is to the
left. If
#of Rotations is negative, the rotation is to
the right. The default is ë 1 (rotate right one bit).
For example, in a right rotation:
In Hex base mode:
rotate(0h78E) ¸ 0h3C7
rotate(0h78E,ë 2) ¸0h800001E3
rotate(0h78E,2) ¸ 0h1E38
0b00000000000001111010110000110101
produces:
0b10000000000000111101011000011010
The result is displayed according to the
Base
mode.
Important: To enter a binary or hexadecimal
number, always use the 0b or 0h prefix (zero,
not the letter O).
rotate( list1 [, #ofRotations ]) ⇒ list
Returns a copy of list1 rotated right or left by #of
Rotations
elements. Does not alter list1 .
If
#of Rotations is positive, the rotation is to the
left. If
#of Rotations is negative, the rotation is to
the right. The default is ë 1 (rotate right one
element).
In Dec base mode:
rotate({1,2,3,4}) ¸
{4 1 2 3}
rotate({1,2,3,4},ë 2) ¸
{3 4 1 2}
rotate({1,2,3,4},1) ¸
{2 3 4 1}
rotate( string1 [, #ofRotations ]) ⇒ string
Returns a copy of string1 rotated right or left by
#of Rotations characters. Does not alter string1 .
If
#of Rotations is positive, the rotation is to the
left. If
#of Rotations is negative, the rotation is to
the right. The default is ë 1 (rotate right one
character).
rotate("abcd") ¸ "dabc"
rotate("abcd",ë 2) ¸ "cdab"
rotate("abcd",1) ¸ "bcda"
round() MATH/Number menu
round( expression1 [, digits ]) ⇒ expression
Returns the argument rounded to the specified
number of digits after the decimal point.
digits must be an integer in the range 0–12. If
digits is not included, returns the argument
rounded to 12 significant digits.
Note: Display digits mode may affect how this is
displayed.
round(1.234567,3) ¸ 1.235
round( list1 [, digits ]) ⇒ list
Returns a list of the elements rounded to the
specified number of digits.
round({p,‡(2),ln(2)},4) ¸
{3.1416 1.4142 .6931}
Rightmost bit rotates to leftmost.
Each bit rotates right.
