cheikh diabang:

In addition if you are going to return several float values, you should put
float[]...

Function calcul_coefficients(x As Integer, y As Integer, degre As Integer)
As Float[]

....
Dim ArrayABC as new float[]
....
.....
ArrayABC.add(A)
ArrayABC.add(B)
ArrayABC.add(C)

Return ArrayABC

Julio
