Hi I'd like to be able to perform some manipulation on NUMERIC values in a C function; however the exposed functionality in numeric.h is pretty restrictive. I can see numeric_normalize will return a pointer to a string representation, which is workable, and if there were an equivalent string-to-numeric function that would be enough (although not the most efficient) but I can't see a way to get a string back in to a numeric value to return. numeric_in looks like it might do what I want but to do that I would have to build a FunctionCallInfo struct to do that, and I'm not 100% clear how to do that either :( I _could_ return the result as a varchar and cast it back to numeric in the SQL, but that's not very clean. Accessing the numeric structure directly would work too but I'm assuming that's not recommended since it's not exposed in numeric.h. Any thoughts would be appreciated, Geoff
