number-crunching: n. [common] Computations of a numerical
nature, esp. 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, esp. if it involves ray tracing or
fractals or some other use that makes pretty pictures, esp. if
such pictures can be used as wallpaper. See also crunch.
