Benchmark: Random Integer Generator (favors numbers closer to 0)

Script Preparation code:

// https://gamedev.stackexchange.com/a/116837
function randIntA1(max, min = 0) {
  return Math.floor(Math.abs(Math.random() - Math.random()) * (1 + max - min) + min);
}
function randIntA2(max, min = 0) {
  return ~~(Math.abs(Math.random() - Math.random()) * (1 + max - min) + min);
}
function randIntB1(max, min = 0) {
  return Math.floor((1 + max - min) * (1 - Math.sqrt(1 - Math.random()))) + min;
}
function randIntB2(max, min = 0) {
  return ~~((1 + max - min) * (1 - Math.sqrt(1 - Math.random()))) + min;
}
