Move an array element from one array position to another
...ve2 = function(pos1, pos2) {
// local variables
var i, tmp;
// cast input parameters to integers
pos1 = parseInt(pos1, 10);

Is 1.0 a valid output from std::generate_canonical?
...alues happen to round up to IEEE 1.0f but that's just unavoidable when you cast them to IEEE floats. If you want pure mathematical results, use a symbolic computation system; if you are trying to use IEEE floating-point to represent numbers that are within eps of 1, you are in a state of sin.
