范围内的随机数不是随机的

Question

I've been trying to generate random numbers between 1 and 10 million, but was finding that none of the numbers generated were lower than 1 million. I wrote this code to test the problem. This code selects ten million random numbers between 1 and ten million and outputs the lowest number. I'd expect to get at least something in the 100-1000 range at least, but it;s always at least 1 million. What have I missed?

JSFiddle: https://jsfiddle.net/vhLoqz8g/

 var lowest=10000000; for (let i = 0; i < 10000000; i++) { var g=Math.floor(Math.random() * (10000000 - 1 + 1)) + 1; if (g<lowest) { lowest=g; } } document.write(g);

Answer 1

You should output lowest and not g at the end of your loop:

 var lowest=1e8; for (let i = 0; i < 1e7; i++) { var g=Math.floor(Math.random()* 1e7) + 1; if (g<lowest) lowest=g; } console.log(lowest)
