Method
Adds two BCD numbers together.
Category
BCD
Syntax
Function BcdAdd(ByVal hDstBcd As Long, ByVal hSrcBcd As Long) As
Long
hDstBcd
The handle to the destination BCD number.
hSrcBcd
The handle to the source BCD number.
Example
hBCD = CF1.AllocBcd
hBCD2 = CF1.AllocBcd
tmpLong = 6
tmpLong2 = 3
CF1.LongToBcd tmpLong, hBCD
CF1.LongToBcd tmpLong2, hBCD2
tmpVar = CF1.BcdAdd(hBCD, hBCD2)
tmpVar2 = CF1.BcdToLong(hBCD)
If VarType(tmpVar) = vbLong And CLng(tmpVar2) = tmpLong + tmpLong2 Then
logWr "BcdAdd OK"
Else
logWr "BcdAdd failed"
End If
CF1.FreeBcd hBCD
CF1.FreeBcd hBCD2
Comments
BcdAdd adds the BCD numbers hDstBcd and hSrcBcd together, and
places the result in the BCD number hDstBcd.
For convenience, the function also returns a handle to the BCD number hDstBcd. This is useful in situations where the result is used to call yet another function, as in the following example:
h = BcdAdd(BcdAdd(dst, src),src1)
h and dst are now the same handle, and that handle refers to a BCD number with the value: (dst + src) + src1.
