/* DEC *DivideDecimalAndTruncate(dst,src1,src2,nid);
|
|
*
|
|
* ARGUMENT
|
|
* DEC *dst;
|
|
* DEC *src1,*src2;
|
|
* int nid;
|
|
*
|
|
* DESCRIPTION
|
|
* Divides src1 by src2, storing the result in dst. The quotient is
|
|
* calculated to nid decimal places.
|
|
*
|
|
* RETURNS
|
|
* Returns pointer to dst if successful, otherwise a GM_NULL. The
|
|
* type error (GM_OVERFLOW, GM_UNDERFLOW, GM_NOMEMORY) is in wGMError
|
|
* if wGMError doesn't contain a previous error.
|
|
*
|
|
* POSSIBLE ERROR CODES
|
|
*
|
|
* GM_NULLPOINTER
|
|
* GM_OVERFLOW
|
|
* GM_UNDERFLOW
|
|
* GM_DIV0
|
|
* GM_INVALIDID
