How do i convert maxdsiz from hex to integer value

Matthew_50 — Wed, 22 Jul 2009 16:06:47 GMT

Hello experts

From current kernel,
kmtune|grep maxdsiz
maxdsiz 0x90000000 - 0X90000000
maxdsiz_64bit 0x100000000 - 0X100000000

How do I calculate 0x90000000 & 0x100000000 into integer value ?

Thank you.

Matthew

you can use the calculator scientific mode (on a windows workstation).
select Hex
enter the value
click on Dec

you get the integer value.

Hi Matthew:

There's always Perl, too:

# perl -e 'printf "%d\n",0x100000000'
4294967296

...and Perl has no artificial limits.

so, the value is hex in kernel right ?
as check from hpux 11.0 11.11 have this format. but in hpux 11.23 never see this format.

Hi (again):

> so, the value is hex in kernel right ?

The notation '0x' means hexadecimal.

By the way, a leading zero (0) in a series of numbers means octal. Hence, 0777 is an octal value whereas 777 would be a decimal number and 0x777 would be a hexadecimal one.

With 11.23 ksh you can do:
$ typeset -i10 x=16#90000000; echo $x
2415919104
(Unfortunately the Posix shell is limited to 32 bits. )-:

You can also use gdb to act as a calculator.
(gdb) p 0x90000000
