Hi, many thanks... I just want to test the validity of some lower
precision results with results generated by increasing levels of precision.
Would defining the matrix entries as -1.0 4.0 1.0 do the trick to force
floats?
In Maple--yes. If you do this in Mathematica you're well-advised to
use a notation like N[-1,64], N[4, 64], N[1,64]. The "4.0" will be
read as a standard double-precision floating-point number.
(Mathematica doesn't have a "Digits" command--each number has its own
intrinsic precision.)
But you asked about Maple, not Mathematica, so this is just for your
general edification...
