Casio fx-9750GIII: Spin the Wheel

Casio fx-9750GIII:   Spin the Wheel



Making the Wheel and String Commands


The wheel is comprised of a long string.  Each space has an equal amount of characters, in this case I picked 5.  To make the wheel "spin", I use the StrRotate.


StrRotate(Str n, s):


Str n:  n from 1 to 20

s:  number of spaces to rotate the string.  If s>0 the string rotates left.  If s<0, the string rotates right.   The characters wrap around.  


If Str1 = "TESTBOOKADAM"


StrRotate(Str 1,4) returns "BOOKADAMTEST"

StrRotate(Str 1,-4) returns "ADAMTESTBOOK"


Other commands used:


StrLeft(Str n, s):   takes the left s characters of Str n

StrRight(Str n, s):  takes the right s characters of Str n

StrMid(Str n, p, m):  extracts the string starting at position n at m characters



The wheel used in this program:
