Rounddown formula

Hi,

I have a calculator from excel and I want to implement it to your plugin.

Formula in excel
C1 =ROUNDDOWN(SUM(607.5/A1),0)
D1 =ROUNDDOWN(SUM(407.5/B1),0)
E3 =SUM(C1*D1)
F1 =SUM(215/E1)
G1 =SUM(F1+1)
H1 =SUM(F1+0.75)
I1 =SUM(F1+0.5)
J1 =SUM(F1+0.251)

Calculated Fields Form
A1: [fieldname1] = C1: [calculatedfield1]
B1: [fieldname2] = D1: [calculatedfield2]
E3: [calculatedfield3]

F1: [calculatedfield4]
G1: [calculatedfield5]
H1: [calculatedfield6]
I1: [calculatedfield7]
J1: [calculatedfield8]

F1 + G1 + H1 + I1 + J1 = [calculatedfield9]

Thanks!
