fsolve with financial functions

[DrD]

fsolve((Finance::TvmFV(48,x,0,-100,12,12,0)) = 5000,x) is an interesting construct, but if it was designed to work that way, I haven't seen it.

Of course something like this could be used, instead:

X:=5000;

[CAS]
Finance::TvmIPYR(48,0,-100,X,12,12,0);
-or-
[Home] or [CAS]
Finance.TvmIPYR(48,0,-100,X,12,12,0);
