Faker.js random number between 2 values
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
I encounter this warning while running faker.random.number
in my application [email protected]
.
Deprecation Warning: faker.random.number is now located in faker.datatype.number
The methods have been moved. A better fix would be replaced with faker.datatype.number()
.
faker.datatype.number(100); // return 88
faker.datatype.number({ min: 5, max: 10 }); // return 7
From Fakerjs github
Whole Number faker. random.number(min,max) Random number between 0 and "range".
faker.random.number(100); //returns 92
faker.random.number({min:5, max:10}); //returns 9
Decimal number faker. finance.amount(min,max,decimal places) Random number between "min" and "max" including decimals to X digits.
faker.finance.amount(9000,10000,4); //returns 9948.8363
Boolean faker. random.boolean()
faker.random.boolean(); //returns true
Array Element faker. random.arrayElement(array[]) Selects a random element from an array of possible values. This function is useful to create custom lists of possibilities.
faker.random.arrayElement(["one","two","three","four"]); //returns "two"
var phTyp = faker.random.arrayElement(["cell","work","home"]); //returns "work"
Object Element faker. random.objectElement(object{}) Selects a random element from an object, selects the value not the keys. This function is useful to create custom lists of possibilities.
faker.random.objectElement({one: 1, two: 2, three: 3}); //returns 3
