Subject: common: Use the correct magic number in Fixed15_49::pi_div_two().
X-Git-Url: http://git.code-monkey.de/?a=commitdiff_plain;h=853beae392e40ee2843e7187500285da666f11e9;p=gps-watch.git

common: Use the correct magic number in Fixed15_49::pi_div_two().

This change should fix the display of current distance travelled
during a workout. It does not affect recordings.
