HP Prime Graphing NW280AAABA manual Changing the default base, Binary, Octal, Decimal or Hex

Note that if you change the default base, any calculation in history that involves integer arithmetic for which you did not explicitly add a base marker will be resisplayed in the new base. In the example at the right, the first calculation explicitly

included base markers (b for each operand). The second calculation was a copy of the first but without the base markers. The default base was then changed to hex. The first calculation remained as it was, while the second—without base markers being explicitly added to the operands—was redisplayed in base 16.

Changing the default base

The calculator’s default base for integer arithmetic is 16 (hexadecimal). To change the default base:

1.Display the Home Settings screen:

SH

2.Choose the base you want from the Integers menu:

Binary, Octal, Decimal or Hex.

3.The field to the right of Integers is the wordsize field. This is the maximum number of bits that can

represent an integer. The default value is 32, but you can change it to any value between 1 and 64.

4.If you want to allow for signed integers, select the ± option to the right of the wordsize field. Choosing this option reduces the maximum size of an integer to one bit less than the wordsize.
