The double(A) function evaluates each element of A numerically at a precision of Digits:=15.  If possible, the computation is done using the floating-point hardware of the underlying system using evalhf.  The evaluation is done in double precision.

Division by zero will be trapped and Float(infinity) returned instead of raising an error.
