number crunching
     
         Computations of a numerical nature,
        especially those that make extensive use of {floating-point}
        numbers.  The only thing {Fortrash} is good for.
     
        This term is in widespread informal use outside hackerdom and
        even in mainstream slang, but has additional hackish
        connotations: namely, that the computations are mindless and
        involve massive use of {brute force}.  This is not always
        {evil}, especially if it involves {ray tracing} or {fractal}s
        or some other use that makes {pretty pictures}, especially if
        such pictures can be used as {wallpaper}.
     
        See also {crunch}.
