HEX
Type: Command
Description: Hexadecimal Mode Command: Selects hexadecimal base for binary integer operations. (The

automatically show the suffix h. If the current base is not hexadecimal, then you can enter a
hexadecimal number by ending it with h. It will be displayed in the current base when it is
entered.
The current base does not affect the internal representation of binary integers as unsigned binary
numbers.
