Ken,

in Release 4 running the below in Console mode I get

DIM FV as double
DIM n as int
DIM r as double
DIM P as INT

'FV = $1500 *(1 + 0.05)20 = $3975.94

P = 1500
r = .05
n = 20

'There is only one problem: This does not equate properly in FB^3, nor does:

FV = P*(1 + r)^n


Print FV  // = 3979.9465577


is that not right?
