Numbers in Different Bases
Besides our decimal (base 10, digits = 0-9) number system, you can work
with a binary system (base 2, digits = 0,1), an octal system (base 8, digits =
0-7), or a hexadecimal system (base 16, digits=0-9,A-F), among others. The
same way that the decimal integer 321 means 3x10
number 100110, in binary notation, means
= 32+0+0+4+2+0 = 38.

With system flag 117 set to SOFT menus, the BASE menu shows the following:
This figure shows that the LOGIC, BIT, and BYTE entries within the BASE menu
are themselves sub-menus. These menus are discussed in detail in Chapter 19
of the calculator's user's guide.
Writing non-decimal numbers
Numbers in non-decimal systems, referred to as binary integers, are written
preceded by the # symbol („â) in the calculator. To select the current
base to be used for binary integers, choose either HEX(adecimal), DEC(imal),
