[Gambas-user] Math Operation

[cheikh diabang]

Hi ! i wanna know how recover return value of function in my case.

I do that as below, but he said object expected

 calcul_coefficients(j, iy_v_c_w, 2)
                               coeff_v_c_w_0 = calcul_coefficients[2]
                               coeff_v_c_w_1 = calcul_coefficients[1]
                               coeff_v_c_w_2 = calcul_coefficients[0]

Thank for help.

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



Regards,

Julio
