Not only in ms. It is the general convention accepted in ILP32 and LP64 programming models, which glpk conforms to. For more details please see: http://www.unix.org/version2/whatsnew/lp64_wp.html . > If the value of the unsigned > int t is greater than maximum unsigned short, how will x[i+j] = > (unsigned short)t; be executed? Since t is unsigned int, (unsigned short)t is its lower 16 bits, i.e. it is the same as t % 65536U or t & 0xFFFFU. FYI: The routines bigmul and bigdiv implement algorithms from "The Art of Computer Programming" by Don Knuth (the second volume).
