You can always enter numbers in octal, decimal, or hexadecimal in GDB by
the usual conventions: octal numbers begin with `0', decimal
numbers end with `.', and hexadecimal numbers begin with `0x'.
Numbers that begin with none of these are, by default, entered in base
10; likewise, the default display for numbers--when no particular
format is specified--is base 10. You can change the default base for
both input and output with the
set radix command.
set input-radix base
set radix 012 set radix 10. set radix 0xasets the base to decimal. On the other hand, `set radix 10' leaves the radix unchanged no matter what it was.
