Subject: Re: [pbs-devel] [PATCH proxmox-backup 2/2] fix division by zero
Date: Fri, 24 Jul 2020 09:15:33 +0200 (CEST)	[thread overview]
Message-ID: <1013805395.481.1595574934177@webmail.proxmox.com> (raw)
In-Reply-To: <20200723161637.6280-3-s.ivanov@proxmox.com>

Why do we use duration.as_secs() here?

We can do better by using floating point values using duration.as_secs_f64() to calculate
the speed more exactly.
