[GENERAL] formatting the output of a function

[Islam Hegazy]

Hi all

I created a function that returns a set of records. This function returns an 
integer and a float as the record fields. I have a problem in this function, it 
truncates the output. e.g. 1342 is displayed as 134, 456.46 is displayed as 
456. In other words, it displays the first 3 digits only of a number, whether 
it is integer of float. I traced the function and the results are computed 
correctly. I use PostgreSQL 8.2.4. Following is a piece of my code.

int counter;

float  result;

//some code

char **output;

output = (char**)palloc(2*sizeof(char*)); //allocate space for two string 
pointer

output[0] = (char*)palloc(sizeof(int)); //allocate space for a string that 
accepts an integer

output[1] = (char*)palloc(sizeof(double)); //allocate space for a string that 
accepts an integer

snprintf(output[0], sizeof(int), "%d", counter);

snprintf(output[1], sizeof(float), "%.5f", result);


HeapTuple data;

Datum finalResult;

data = BuildTupleFromCStrings(attinmeta, output);

finalResult = HeapTupleGetDatum(data);

SRF_RETURN_NEXT(funcctx, finalResult);

---------------

Any idea what could be the cause of this error?
