JavaScript Random Number Value method

The Math.random () method returns a random number from 0 to 1, excluding 0 and 1

If you want to take a range of random numbers, you can apply the following formula:

I. x+ start number -1= end number

Two. Math.floor (Math.random () *x+ start number) Note: Math.floor () rounded down, minus the number of decimal points

Cases:

To take a number from 5 to 10, apply the formula: ①x+ start number -1= end number
It can be concluded that X is 6
②math.floor (Math.random () *x+ start number)
//
for (Var i=0;i<10;i++) {
document.write (Math.floor (Math.random () *6+5));
document.write (' <br/> ')
}
