I'm not a professional dba or dbd, but I'm proficient in the basics of
database design and sql. I want to create a database of math
definitions, and I'm wondering how one would go about creating a
database that contains mathematical notation (and I'm not just talking
about basic symbols where I could get away with ascii code). I need
to be able to insert a wide variety of mathematical expressions, from
fractions to integrals, into fields (just like you can enter in-line
math symbols in MS Word using equation editor). I have no clue how to
go about this. Is it a matter of developing certain programming
skills/languages? Would such a capabliltiy be proprietary (dbms-
specific)? Is it possible at all? Any help would be appreciated.
Thank you.

>MathML is based on XML <<
How is this standard doing? I think I might be behind the curve,
since I have not done any math writing in a very long time. LaTEX was
the standard in the US for the American Mathematical Association
papers and other journals. It was also popular with textbook
publishers because you could get Knuth's Metafont symbols for
typesetting.

One way to implement this is to use the Mathematical Markup Language
(MathML). MathML is based on XML and is used for describing mathematical
notation and encoding both its structure and content. The main purpose of
MathML is to enable mathematics to be used on Internet, but since it is XML
based it is widely used in applications that can process XML.
SQL Server supports Unicode and also SQL Server 2005 adds support for XML
data type. There are many parsers, and any browser can serve as presentation
layer.
See more info on the official W3C site at the links below:http://www.w3.org/Math/whatIsMathML....SL/csmall2.xml
I have seen some applications that use MathML to store mathematical
notations, but developed in Oracle (still storing in XML columns).

Javascript has a very small math function list. However there is no
reason that this list can not be extended greatly. Speed is not an
issue, unless you nest complicated calculations several levels deep. In
that case you need much more ram than a PC has to store functions
calculated in loops so that you do not have to recalculate every time
you cycle through the nest of loops. Using a HD for storage to extend
ram is much too slow for many...

Hello,
Does anyone know if there is a library or a sample project that can
parse strings with mathematical expressions inside ?
eg. string math = "(23 + 48) ^ 2 - (7.76 * 3.14)";
parser should calculate the result of this.
Atm I have my own parser, but it can only handle very simple
expressions with 2 operands eg. (34 * 89), I tried to expand the

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
