Package: catdoc
Version: 0.94.2-1
Severity: important
Tags: patch
On amd64 using xls2csv negative numbers are exported as huge positive numbers
I believe the real problem is in xls.parse.c:format_rk
which should be:
#include <stdio.h>
....
if ( *(rec) & 0x02 )
{
int32_t ival=getlong((unsigned char *)rec,0);
value=(double)(ival>>2);
}
But there are many typecast issues, I tried to handle some of them:
