I have a hard time believing you have implemented the semantics that people
have agreed on to be a sensible semantics for hybrid sets.
Noted.

There's two options I think:

The former will require more organisation, partly because we need the

Hello,
Up until now I've been using Aeson, but I've found that its number type
isn't going to work for me. I need to use decimal numbers while avoiding
conversions from and to Double, which Aeson doesn't allow. There are
quite a few more JSON libraries for Haskell, which all appear to use
initIdentityMat :: Int - ST s (STUArray s (Int,Int) ((Int, Int), Double))
initIdentityMat m = newListArray ((1,m),(1,m)) ([((i,j), if i == j then 1.0
else 0.0) | i - [1..m], j - [1..m]] :: [((Int,Int), Double)])
Doesn't seem to compile, nor do minor variations of the type declaration.

Hello,
I could be wrong, but I think the only real numeric type in javascript
is 'Number' which is a floating point number? Which is why Aeson and
others insist on converting everything to a Double or other Rational
number?

Hi Jeremy,
Sorry if I was unclear. Rational is acceptable to me as the result of a
JSON parse, but Double (which Aeson uses), is not. Also acceptable would
be Data.Decimal.Decimal, or maybe one of the types from Data.Fixed.
JSON doesn't specify a data type for numbers, only a format.
Jeff
JSON numbers are not equivalent to JavaScript/ECMAScript numbers, even if
they are nominally related; the key differences are that in JSON, numeric
literals:
(a) can have any non-zero number of digits, effectively making JSON numbers
both unbounded and arbitrarily precise (though actual
Your problem is that you're including the (i, j) in your array element
type, when you really only want it to be in your index type (I assume).
This would not normally be an issue, but an unboxed array doesn't work on
an element type of ((Int, Int), Double).
You might consider instead making a new

Hello,
Have you emailed Bryan O'Sullivan and explained your problem? It
sounds to me like choosing Double was just the wrong choice and is a
design flaw that should be fixed in Aeson?
There are far too many JSON libraries on hackage already, and what

For various reasons, some packages don't build documentation on hackage:

Sjoerd,
This is not just about map, but it also a problem for the Monoid instance. You
are basically adding an extra identity element, 0, to the max monoid, which
works but is weird.
Still that's how union is typically defined for hybrid sets.
