Random number between -10 and 10 in JavaScript [duplicate]

Answer 1

For example:

var min = -10;
var max = 10;

console.log(Math.floor(Math.random() * (max - min + 1) + min));

.as-console-wrapper { max-height: 100% !important; top: 0; }

See this jsrandom.php for some comparison of Math.floor, Math.ceil and Math.round.
