>> From: Jim Moser "jmoser"
I'm using the Scientific Workplace implementation of Maple. I recently
encountered a problem and wondered whether the problem is unique to that
implementation or is with Maple.
The problem is checking for equality of expressions having summations at
discrete intervals (FORTRAN e.g. i=1,10) . I found that two step were
necessary. The comparison isn't done at all unless each expression is
first numerically evaluated. Then because the evaluation produces
floating point rather than integer (in the FORTRAN sense), I must delete
the occurrence of ".0" in discrete variables to force the comparison to
treat those variables correctly.
Seems that what is missing is a convention (or preference setting) that
forces Maple, at least the SWP implementation of Maple, to regard
select variables as discrete. I'd appreciate confirmation of this
"explanation." And while at it, if anyone can suggest an improvement to
my work around, I'm all ears.
