Faker.js random number between 2 values

rated 0 times [ 0] [ 7] / answers: 1 / hits: 104654 / 9 Years ago, fri, august 14, 2015, 12:00:00

This one is driving me a little mad, I'm sure it's simple but it doesn't seem to be documented anywhere.

Im using Faker.js and the following to generate my random number:

faker.random.number();

Works great, now if I want to do it between 2 numbers, how would I go about this?

I tried the following:

faker.random.number(10, 50);

However, that just gives me numbers from 0 to 10. No idea what the 50 is doing.

Can anyone give me some directions to this please.

You need to give an object to the function:

faker.datatype.number({

    'min': 10,

    'max': 50

});

So if you just pass a number, it will set it as the max value. The min value is 0 by default.

This is the implementation of the number function :

this.number = function (options) {



    if (typeof options === "number") {

      options = {

        max: options

      };

    }



    options = options || {};



    if (typeof options.min === "undefined") {

      options.min = 0;

    }



    if (typeof options.max === "undefined") {

      options.max = 99999;

    }

    if (typeof options.precision === "undefined") {

      options.precision = 1;

    }



    // Make the range inclusive of the max value

    var max = options.max;

    if (max >= 0) {

      max += options.precision;

    }



    var randomNumber = options.precision * Math.floor(

      mersenne.rand(max / options.precision, options.min / options.precision));



    return randomNumber;



  }

Update

Latest versions changed location of the function from faker.random.number to faker.datatype.number, https://github.com/Marak/faker.js/issues/1156
