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.
