Using @fastmath

General Usage Performance
1

Hi, I have started to use @fastmath to have fast computations for polynomials. It was great when I pass Float64. But when i pass dual number (e.g. ForwardDiff.Dual(1., 1.)), i noticed that there is no any speed up.

Do you have any suggestions?

Thank You.

can you give us an example. But in general, @fastmath can only transform the expression it sees directly and also it doesnt know anything about the dual numbers
