[Haskell-beginners] hmatrix, and Float

[MAN]

I noticed that hmatrix defines the auxiliary type 'Element', and
provides instances for Double and Complex, but not Float. Then Vector
and Matrix are defined in terms of Element... is there any reason why
Float is intentionally left out.

I'd like to use Numeric.LinearAlgebra with both single and double
precision so as to compare results and times... could I?
