Hi, I was trying to fix failing test of r.profile: http://fatra.cnr.ncsu.edu/grassgistests/reports_for_date-2014-10-19-07-00/report_for_nc_spm_08_grass7_nc/raster/r.profile/test_profile_ncspm/index.html
which is working on 32-bit machine. I committed this change: http://trac.osgeo.org/grass/changeset/62299 which fixed it but I was wondering, if r.profile shouldn't use atan2 instead of atan? It seems that the division in atan could possibly lead to overflow? But nobody complained about it yet... Tests work with atan2. Thanks, Anna
