101

Extracts n characters from string str starting at index pos. n is optional, if not specied, extracts all the

remainder of the string.

Example: MID("MOMOGUMBO",3,5) returns "MOGUM", MID("PUDGE",4) returns "GE"

ROTATE

Syntax: ROTATE(str,n)

Permutation of characters in string str. If 0 <=n < DIM(str), shifts n places to left. If –DIM(str) < n <= –1, shifts

n spaces to right. If n > DIM(str) or n < –DIM(str), returns str.

Examples:

ROTATE("12345",2) returns "34512"

ROTATE("12345",-1) returns "51234"

ROTATE("12345",6) returns "12345"

STRINGFROMID

Syntax: STRINGFROMID(integer)

Returns, in the current language, the built-in string associated in the internal string table with the specied

integer.

Examples:

STRINGFROMID(56) returns “Complex”

STRINGFROMID(202) returns “Real”

REPLACE

Syntax: REPLACE(object1, start, object2)

Replaces part of object1 with object2 beginning at start. The objects can be matrices, vectors, or stings.

Example:

REPLACE("12345",”3”,”99”) returns "12995"

Drawing

There are 10 built-in graphics variables in the HP Prime, called G0–G9. G0 is always the current screen graphic.

G1 to G9 can be used to store temporary graphic objects (called GROBs for short) when programming

applications that use graphics. They are temporary and thus cleared when the calculator turns o.

Twenty-six functions can be used to modify graphics variables. Thirteen of them work with Cartesian

coordinates using the Cartesian plane dened in the current app by the variables Xmin, Xmax, Ymin, and

Ymax.

The remaining thirteen work with pixel coordinates where the pixel 0,0 is the top left pixel of the GROB, and

320, 240 is the bottom right. Functions in this second set have a _P suix to the function name.

C→PX

Converts from Cartesian coordinates to screen coordinates.

Syntax: C→PX(x,y) or C→PX({x,y})
