/* DEC *AddDoubleToDecimal(pDst,pSrc1,l)
|
|
*
|
|
* ARGUMENT
|
|
* pDst is a pointer to the destination DEC structure.
|
|
* pSrc1 is a ptr to the source1 DEC structure.
|
|
* l is the double to be added to pSrc1
|
|
*
|
|
* DESCRIPTION
|
|
* Adds the value 'l' to pSrc1 and puts the result in dest DEC structure.
|
|
* The sum is calculated to the maximum possible accuracy.
|
|
*
|
|
* SIDE EFFECTS
|
|
* On overflow, the dest value is destroyed.
|
|
*
|
|
* RETURNS
|
|
* Returns a pointer to the dest structure unless overflow,
|
|
* when it returns a GM_NULL. On error, the error
|
|
* is in wGMError, unless an error was already there.
|
|
*
|
|
* POSSIBLE ERROR CODES
|
|
*
|
|
* GM_NULLPOINTER
|
|
* GM_OVERFLOW
|
|
* GM_CNVRE
