/* DEC DivideAscii(pDst,pSrc1,pSrc2)
|
|
*
|
|
* ARGUMENT
|
|
* pDst is a poiter to the destination DEC structure
|
|
* pSrc1 is a pointer to source1 ASCII string
|
|
* pSrc2 is a pointer to source2 ASCII string
|
|
*
|
|
* DESCRIPTION
|
|
* Divides ConvAsciiToDecimal(pSrc1)/ConvAsciiToDecimal(pSrc2)
|
|
* = pDst DEC structure.
|
|
*
|
|
* SIDE EFFECTS
|
|
* On error, the value of the dest structure is undetermined.
|
|
*
|
|
* RETURNS
|
|
* Returns a pointer to the dest structure on success,
|
|
* otherwise returns a GM_NULL(a C false). On error, the error
|
|
* is in wGMError, unless an error was already there.
|
|
*
