Create 4 new formats enums rtl_math_StringFormat: rtl_math_StringFormat_E1, rtl_math_StringFormat_E2, rtl_math_StringFormat_G1, rtl_math_StringFormat_G2 to 1 or 2 digits in exponent for scientific notation. Set General format to use rtl_math_StringFormat_E2. Set trendline equation in status bar to use rtl_math_StringFormat_E1 Change-Id: I41466a6d4ba808ba5b9b38ba252b37c6b4560f12 Reviewed-on: https://gerrit.libreoffice.org/14562 Reviewed-by: Eike Rathke <erack@redhat.com> Tested-by: Eike Rathke <erack@redhat.com>
