The code of most Calc functions is in sc/source/core/tool/interpr#.cxx,
with # ranging from 1 to 8.
In sc/source/core/tool/interpr4.cxx is a function
ScInterpreter::Interpret() with a large switch statement which handles
the function calls. E.g. 'case ocSum : ScSum(); break;' shows that the
SUM function is ScSum, which git grep (or opengrok) tells you is in
Some functions belong to a group 'Add-in functions' and are essentially
functions that Excel had as a special package. These are handled quite
differently and in scaddins/source/analysis and scaddins/source/financial.
