From 295b1b78d888b528f7a5a23411b1a82d4b39eed1 Mon Sep 17 00:00:00 2001 From: "Robert C. Helling" Date: Fri, 10 Mar 2017 07:22:31 +0100 Subject: Make depth conversion work for negative depths This is needed in the altitude pressure conversion as there negative altitudes are possible (for diving in the netherlands or the Dead Sea).
