Question:Float(undefined) error?

Hi,

I want to compute a define integral as follows:

> restart:

> k:=.73*10^16:

> g:=46:

> R:=.4387053103e-13:

> f:=r -> .1121524131e-12/(1+exp(.4000000000e16*r-47.29107172)):

> S:=.07+I*.66:

> X:=r->(1-Re(S*exp(2*I*(k*r-g*ln(2*k*r))))):

> int(X(r)*f(r) , r=R..infinity);

But I don’t understand why the Float(undefined) error appears. Is it possible to revise it?

With best regards,

Werner Melzer
