Shade CATALOG
Shade expr1 , expr2 , [ xlow ], [ xhigh ], [ pattern ], [ patRes ]
Displays the Graph screen, graphs expr1 and
expr2 , and shades areas in which expr1 is less than
expr2 . ( expr1 and expr2 must be expressions that
use x as the independent variable.)
xlow and xhigh , if included, specify left and right
boundaries for the shading. Valid inputs are
between
xmin and xmax . Defaults are xmin and
xmax .
pattern specifies one of four shading patterns:
1 = vertical (default)
2 = horizontal
3 = negative-slope 45
¡
4 = positive-slope 45 ¡
patRes specifies the resolution of the shading
patterns:
1= solid shading
2= 1 pixel spacing (default)
3= 2 pixels spacing
©
10= 9 pixels spacing
Note: Interactive shading is available on the
Graph screen through the
Shade instruction.
Automatic shading of a specific function is
available through the
Style instruction. Shade is
not valid in 3D graphing mode.

shift() CATALOG
shift( integer1 [, #ofShifts ]) ⇒ ⇒ ⇒ ⇒ integer
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:
In Bin base mode:
shift(0b1111010110000110101) ¸
0b111101011000011010
shift(256,1) ¸
0b1000000000
In Hex base mode:
shift(0h78E) ¸ 0h3C7
shift(0h78E,ë2) ¸ 0h1E3
shift(0h78E,2) ¸ 0h1E38
Important: To enter a binary or hexadecimal
number, always use the 0b or 0h prefix (zero,
not the letter O).
