right(
list1
[
,
num
]
)
⇒
list
Returns the rightmost
num
elements contained in
list1
.
If you omit
num
, returns all of
list1
.

)
⇒
string
Returns the rightmost
num
characters contained in
character string
sourceString
.
If you omit

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).
Rightmost bit rotates to leftmost.
Each bit rotates right.
