Float

The library is used to create a float data type with its own set of methods.

The Float() function can be called as a constructor with or without a parameter. In both cases, it will return an instance of Float with the value property, where the value will be a fractional number. In the latter case, the value of this property will be a random fractional number.

// 1
let float1 = new Float();
console.log(float1); // Float { value: random fractional number }
console.log(float1.value); // random fractional number

// 2
let float2 = new Float(-1.7);
console.log(float2); // Float { value: -1.7 }

Also Float() can be called as a normal function and work similarly as if Float.random() is called.

let float3 = Float();
console.log(float3); // random fractional number

The typeof operator does not return the float data type in this library.

console.log(typeof float1); // "object"
console.log(typeof float3); // "number"

Methods

Float.prototype.toFixed()

Works similarly to Number.prototype.toFixed().

let float4 = new Float(1.234);
console.log(float4); // Float { value: 1.234 }
console.log(
    float4.toFixed(), // Float { value: "1" }
);

Float.random([min, max])

Generates a random fractional number.

let float5 = Float.random(20, 21);
console.log(float5); // some fractional number between 20 inclusive and 21 not inclusive.

Float.is()

Returns true if the passed value is an instance of Float or a fractional number primitive.

console.log(
    Float.is(123), // false
    Float.is("12.3"), // false
    Float.is("1.5.5"), // false
    Float.is(float1), // true
    Float.is(float2), // true
    Float.is(float3), // true
);

Float.like()

Returns true in all cases of true for Float.is(), and also if the passed value is a string consisting entirely of a fractional number.

console.log(Float.like("12.3")); // true

How to install

1. Install the library into your project using the command - npm i float_data_type.
2. The library uses CommonJS modules. Connect the module to your file as follows: const { Float } = require('float_data_type');
