Number generator based on a text input with vague random properties

In short, the generator produces random values that are predictable and can be repeated.

Install

$ npm install --save dazzling-chance

Create your chance

This will create a chance object with:

• text: an input text used for generating the numbers in a predictable way.
• characters: a list of characters with their mapping to a number.
• weighting (optional): a list of weights to bend the luck a little bit.

var dazzlingChance = require('dazzling-chance');

       var chance = dazzlingChance({
            text: "qwertyuopasdfghjklzxcvbnm",
            characters: [{
                chars: "0-9a-z",
                integer: 0
            }],
            weighting: [{
                name: "fibonacci",
                weights: [1, 2, 3, 5, 8, 13, 21, 2]
            }]

        });

Create a float number between min and max

chance.nextFloat(0, 3))

Or using a weight:

chance.nextWeightedFloat('fibonacci', 0, 3)

Create an int number between min and max

chance.nextInt(0, 3))

Or using a weight:

chance.nextWeightedInt('fibonacci', 0, 3))

Create a boolean

chance.nextBool()

Or using a weight:

chance.nextWeightedBool('fibonacci')

Create a string from a given list

chance.nextString(['a', 'b', 'c', 'd', 'e'])

Or using a weight:

chance.nextWeightedString('fibonacci', ['a', 'b', 'c', 'd', 'e'])

Create a number from a given list

chance.nextNumber([36, 47, 3, 68, 34])

Or using a weight:

chance.nextWeightedNumber('fibonacci', [36, 47, 3, 68, 34]), 'A')

Create the next random value

type can be: 'int', 'float', 'number', 'bool', 'string'

chance.next({
            type: 'float',
            weight: 'fibonacci',
            min: 0,
            max: 3
        });

Create an array of random values

chance.nextX(4, {
            type: 'float',
            min: 0,
            max: 10
        })

Create a high resolution random value

chance.nextHighRes({
            type: 'float',
            minResolution: 1000,
            min: 0,
            max: 1000
        })

Create an array of high resolution random values

Ex: 10 values

chance.nextHighResX(10, {
            type: 'int',
            minResolution: 1000,
            min: 0,
            max: 1000
        })
