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
2 +2x10 1 +1x10 0 , the
number 100110, in binary notation, means
1x2
5 + 0x2 4 + 0x2 3 + 1x2 2 + 1x2 1 + 0x2 0 = 32+0+0+4+2+0 = 38.
The BASE menu
The BASE menu is accessible through ‚ã(the 3 key). With system
flag 117 set to CHOOSE boxes (see Chapter 1 in this guide), the following
entries are available:
With system flag 117 set to SOFT menus, the BASE menu shows the

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
