Adding or multiplying variants in VBA

Question

Suppose we are given two variants, X and Y, that may be numbers, ranges or arrays. Is there a simple way to add or multiply them like in worksheet

Answer 1

After looking at various options, i've settled on a Worksheetfunction method. The most viable candidates for arithmetic calculations appear to be in the financial category. From Excel help on the PV function when rate = 0, the following relation exists among the arguments: pmt * nper + pv + fv = 0. This relation also applies to each of the other corresponding functions. Therefore one option would be:

Sub AddMult()
    Dim X, Y, Add, Mult
    X = Array(Array(1, 3), Array(2, 4))
    Y = Array(1, 2)
    With Application
        Add = .Pmt(, -1, X, Y)
        Mult = .PV(, 1, .PV(, X, Y))
    End With
End Sub

For other operations on variants, further WorksheetFunction methods are available:

.SLN(x,y,1)     'x-y
.SLN(x,,y)      'x/y
.Power(x,y)     'x^y 
.Quotient(x,y)  'x\y 
.Delta(x,y)     'x=y
.GeStep(x,y)    'x>=y

Note: Prefix by Application (not Worksheetfunction which doesn't allow for other data types.)
