I am trying to generate random 0 or 1 as I am writing a script to populdate my database. If it is 1, I will save it as male and 0 the other way around.

Inside my JavaScript:

Math.floor((Math.random() * 1) + 1);

I used this to generate either 1 or 0. However, with the code above, it always return me with 1. Any ideas?

You can use Math.round(Math.random()). If Math.random() generates a number less than 0.5 the result will be 0 otherwise it should be 1.
