How can I generate numbers between 7 to 10? So far all I've figured out is generating in a range from 0-10:
Math.floor(Math.random()*11)
709
Math. random() can never generate 0 because it starts with a non-zero seed. Set the seed to zero, the function does not work, or throws an error. A random number generator always returns a value between 0 and 1, but never equal to one or the other.
Method 1: Using Math. random() function is used to return a floating-point pseudo-random number between range [0,1) , 0 (inclusive) and 1 (exclusive). This random number can then be scaled according to the desired range.
int num = 10; Random rand = new Random(); int ran = rand. nextInt(num); if (ran==0){ ran= ran+1; } System. out. println("random : "+ran);
function getRandom(min, max) {
return min + Math.floor(Math.random() * (max - min + 1));
}
for(var x = 0; x < 5; x++) {
console.log(getRandom(7, 10));
}
Math.floor(7 + Math.random() * 4) will generate numbers from 7 to 10 inclusive.

Just say this:
Math.floor(Math.random()*4) + 7
This will generate a random number from 0-3 and then add 7 to it, to get 7-10.
