Bug#337529: useless bugreport
Hi,
Steffen Schuler wrote:
This bugreport is rather useless:
1.) The contents of /tmp/p is missing. (It can't be the empty file.)
Some copy and paste error.
$cat /tmp/p
0x111
0x112
0x222
2.) The sample [1] below from the bug report only proves that gawk works
correctly.
When interpreting hexadecimal constants in the source code, these
constants
must be prefixed by 0x.
And that's the problem. /tmp/p got prefixed with 0x, but it doesn't work.
Hexadecimal strings can be translated to internal numbers with
strtonum(str)
passing strtonum give the correct output [2].
But that make mawk fails.
3.) The word A in the source code can't be a hexadecimal constant, because
of the missing prefix 0x. It is simply a variable.
Thanks

$cat /tmp/p | gawk '{printf "rr " strtonum($1)-A "\n";A=strtonum($1) }'

Bug#337529: useless bugreport
This bugreport is rather useless:
1.) The contents of /tmp/p is missing. (It can't be the empty file.)
2.) The sample [1] below from the bug report only proves that gawk works
correctly.
When interpreting hexadecimal constants in the source code, these
constants
must be prefixed by 0x.
Hexadecimal strings can be translated to internal numbers with
strtonum(str)
and there is also the gawk-option --non-decimal-data to translate
hexadecimal text in the input, which must be handled with great caution
according to the man-page.
3.) The word A in the source code can't be a hexadecimal constant, because
of the missing prefix 0x. It is simply a variable.
4.) The numbers in /tmp/p1 are surely decimal numbers.
5.) gawk works correctly on this piped input.
