Question

As the title says … is it possible to create a random 16 digit number with jquery?

Answer 1

Just use:

Math.floor(Math.random()*1E16)

EDIT :

Note that there is about a 1/10 chance of a lower number of digits. If Math.random() generates something like 0.0942104924071337 then 0.0942104924071337 * 1E16 is 0942104924071337 which evaluates to 942104924071337; a 15 digit number.

The only way to 100% guarantee that the number is 16 digits in length is to have it be formed as a string. Using this method I would recommend @rjmunro’s answer:

number = (Math.random()+' ').substring(2,10)+(Math.random()+' ').substring(2,10);
