22.6 Numbers
============
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 neither
begin with '0' or '0x', nor end with a '.' 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 commands described below.
'set input-radix BASE'
Set the default base for numeric input. Supported choices for BASE
are decimal 8, 10, or 16. The base must itself be specified either
unambiguously or using the current input radix; for example, any of
set input-radix 012
set input-radix 10.
set input-radix 0xa
sets the input base to decimal. On the other hand, 'set
input-radix 10' leaves the input radix unchanged, no matter what it
was, since '10', being without any leading or trailing signs of its
base, is interpreted in the current radix. Thus, if the current
radix is 16, '10' is interpreted in hex, i.e. as 16 decimal, which
doesn't change the radix.
'set output-radix BASE'
Set the default base for numeric display. Supported choices for
BASE are decimal 8, 10, or 16. The base must itself be specified
either unambiguously or using the current input radix.
'show input-radix'
Display the current default base for numeric input.
'show output-radix'
Display the current default base for numeric display.
'set radix [BASE]'
'show radix'
These commands set and show the default base for both input and
output of numbers. 'set radix' sets the radix of input and output
to the same base; without an argument, it resets the radix back to
its default value of 10.
