Hi all,

I am trying LinearALgebraX package,

the result is quite funny, why there are //1 in all entries?

How to discard all the //1? most people will be confused, unless you are already experienced with Julia and Linear Algebra.

That’s how `Rational` values are printed and that seems to be the main point of LinearAlgebraX:

> This module implements basic linear algebra methods for matrices with exact entries (e.g., `Rational{Int}` values). The function names typically match the standard ones in Julia but with an `x` (for “exact”) appended.

I guess most people who don’t want those `//1` will just use `LinearAlgebra` without the X 😉

Anyways, you can always convert to Float with `convert(Matrix{Float64}, rrefx(A))` or `Float64.(rrefx(A))` - but that will lose the x factor 😉

thanks a lot, I need LinearAlgebraX for its exact entries, just need to get rid of the `//1`

If you need to just get rid of the `//1`, it is more appropriate to write your own `Base.show` method, instead of changing the output type.
