HP Prime Graphing NW280AAABA manual Getbits Syntax GETBITS#integer, If the user taps

GETBITS Syntax: GETBITS(#integer)

Returns the number of bits used by integer, expressed in the default base.

Example: GETBITS(#22122) returns #20h or 32

R→B Syntax: R→B(integer)

Converts a decimal integer (base 10) to an integer in the default base.

Example: R→B(13) returns #1101b (if the default base is binary) or #Dh (if the default base is hexadecimal).

SETBITS Syntax: SETBITS(#integer[m] [,bits])

Sets the number of bits to represent integer. Valid values are in the range –64 to 65. If m or bits is omitted, the default value is used.

Example: SETBITS(#1111b, 15) returns #1111:b15

SETBASE Syntax: SETBASE(#integer[m][c])

Displays integer expressed in base m in whatever base is indicated by c, where c can be 1 (for binary), 2 (for octal), or 3 (for hexadecimal). Parameter m can be b (for binary), d (for decimal), o (for octal), or h (for hexadecimal). If m is omitted, the input is assumed to be in the default base. Likewise, if c is omitted, the output is displayed in the default base.

Examples: SETBASE (#34o,1) returns #11100b while SETBASE (#1101) returns #0h ((if the default base is hexadecimal).

I/O

I/O commands are used for inputting data into a program, and for outputting data from a program. They allow users to interact with programs.

CHOOSE Syntax: CHOOSE(var, "title", "item1", "item2",…,"itemn")

Displays a choose box with the title and containing the choose items. If the user selects an object, the variable whose name is provided will be updated to contain the number of the selected object (an integer, 1, 2, 3, …) or

0 if the user taps .
