C, on the other hand, uses row-major order. The reason the C interface is weird is because MATLAB stores multidimensional arrays in column-major order, like Fortran. You can always use the c interface (which itself is weird, considering matlab's roots in fortran.)

As you can see from the code in the links I posted earlier, a choice of language can hide the fact that the underlying architecture has fixed width arithmetic.Д«TW, for fun, compare the speeds of those two programs, which are implementations of the same algorithm. FYI, the ancient IBM model 1620 computer could do this in hardware. This has been going on since early computers. But the bcd aspect will exist because some kinds of uses for extended precision are financial/money based, and conversion to and from an external decimal format is sufficiently frequent that it's easier/faster to just do the arithmetic directly on decimal, even if tightly squeezed into 4 bits per digit. I can tell you libgmp is not stuck with bcd.

These bounds are not a limit either through library/template facilities at the C/C++ level, or with basic operations in high level (particular object oriented) languages such as Pike and Python. Programming languages like C/C++ perform their basic arithmetic operations at the machine level, so they inherit the same limitations. I'd be interested to see stats of how many people use the 64bit Matlab on computers that natively support 64bit instructionsД¬PU operations are limited to a certain number of bits for their operations. It may just mean that people have tried, found it lacking, and dropped back to 32bit. Much like how a pirated copy does not indicate a lost sale, the fact that only few people have 'demand' for the application, does not mean there's a lack of demand for the functionality in the 64bit program.

Sure they could have looked on the website and found a few basic implementations of Newtonian solve functions written for 64bit, but their response to student complaints was to remove the 64bit Matlab and install the 32bit version. Well at the time the basic add-on packages weren't available for the 64bit version, which included the package with the solve() function. The logical thought was that the computers are 64bit, they have the option, so why not. When our uni upgraded the maths lab computers Matlab versions to R2008a they installed the 64bit version as well. The demand may be there, but it may be masked in the confusion of what may be thought to have been a standard part of the program. 38 downloads may not indicate a lack of demand.
