ODBC claims to only support precisions up to 15, so maybe it's
overreacting to the unsupported precision by truncating the number to an
integer.
Can you try casting the field to a lower-precision numeric and let me
know what happens? For example,
select cast(creditawarded as numeric(10,4))
My matrix package actually only provides semi-persistent (a technical term
in the data structures world, I guess) matrices. A fully functional one
would probably just use a double layered hasheq.
Basically, you can always read any older version of the matrix, but you
only modify the latest modific

Oh! That's related to something I was coding up called "multidim" to
do multi-dimensional matrices. Here is the source

Are you saying that there are fields in your objec
Hello everyone,
I attempting to use the Racket db interface to access a Microsoft SQL Server
2005 database. The field "creditaward" is defined as numeric(19,7), and in the
case of the following query, I should get a value of 1.25 rather than 1. Anyone
have an idea how I get to the fractional pa
My bad, not reading the spec carefully. Should have installed a handler for
exn:fail:resource.

Is there a memory limit that does work? That is, does a 1GB limit work?
2GB? 500MB?

Orthogonal to the type system any unsynchronized parallel read/write is
unsafe.
if (eq? (unbox bx) 3)
(let ((b (unbox bx))

Here assume the type system is not subverted there is a serious lurking
problem nonetheless. Actually larger, as at least if the parallel process

Hi the list,
I'm facing a new problem with Hash parsing with object% keys.
So far, I used (inspect #f) to make public the fields and have the
appropriate equal? response.
But, now I have to had an attribute wich do not have to tested and I
can't figure the best way out.

Yes, 64-bit build.

I have a 64-bit machine and OS with 16GB RAM. I have some benchmarks that I
want to time out after an hour or die if they use 4GB memory.
Unfortunately, the entire VM dies with OOM instead of carrying on. I'm running
from the terminal. Is there some other option I need to pass to not limit the
14 matches
