If you're calculating financial numbers, it may be a good idea to calculate with integers. Count in cents or tenths of a cent with no decimal points, then divide by 10 or 100 to get the dollar result. You won't end up with strange things like negative zero.

btraceback
BTRACEBACK(1) Network backup, recovery and verification BTRACEBACK(1)
NAME
btraceback - wrapper script around gdb and bsmtp
SYNOPSIS
btraceback /path/to/binary pid
DESCRIPTION
btraceback is a wrapper shell script around the gdb debugger (or dbx on Solaris systems) and bsmtp, provided for debugging purposes.
USAGE
btraceback is called by the exception handlers of the Bacula daemons during a crash. It can also be called interactively to view the cur-
rent state of the threads belonging to a process, but this is not recommended unless you are trying to debug a problem (see below).
NOTES
In order to work properly, debugging symbols must be available to the debugger on the system, and gdb, or dbx (on Solaris systems) must be
available in the $PATH.
If the Director or Storage daemon runs under a non-root uid, you will probably need to be modify the btraceback script to elevate privi-
leges for the call to gdb/dbx, to ensure it has the proper permissions to debug when called by the daemon.
Although Bacula's use of btraceback within its exception handlers is always safe, manual or interactive use of btraceback is subject to the
same risks than live debugging of any program, which means it could cause Bacula to crash under rare and abnormal circumstances. Conse-
quently we do not recommend manual use of btraceback in production environments unless it is required for debugging a problem.
ENVIRONMENT
btracback relies on $PATH to find the debugger.
