Number

Number manipulation functions

range

Linear interpolation between two number ranges

  • range (input{array}, output{array}) : {function}
const ceusius = [0, 100];
const fahrenheit = [32, 212];
const convert = _.range(ceusius, fahrenheit);
const result = convert(38);

// result is 100.4
// 38 ceusius is equivalent 100.4 fahrenheit

bezier

Bezier Algorithm

  • bezier (points{array}) : {function}
const b = _.bezier([[0, 0, 0], [1, 1, 1], [2, -3, 6]]);

const pointA = b(0)   // [0, 0, 0]);
const pointB = b(0.5) // [1, -0.25, 2]);
const pointC = b(1)   // [2, -3, 6]);

random

Generate a random number

  • random (min{number}, max{number}, isInt{!boolean}) : {number}
const number = _.random(0, 10);
// number can be any float number between 0 and 10

const int = _.random(0, 10, true);
// int can be any integer number between 0 and 10

randomGenerator

Create a random number generator

  • randomGenerator = (min{number}, max{number}, defaultInt{!boolean}) : {function}
const generator = _.randomGenerator(0, 10);

const floatRandomNumber = generator();
const integerRandomNumber = generator(true);

inRange

Verify if a number is in range

  • inRange (start{number}, end{number}) : {function}
const rangeValidator = _.inRange(0, 10);

const valid = rangeValidator(5);
// valid is true

const notValid = rangeValidator(15);
// notValid is false

zeroPad

Adds zeros to the left of a number

  • zeroPad (number{number}, zeros{number} = 2) : {string}
_.zeroPad(2);
// 02

_.zeroPad(10);
// 10

_.zeroPad(10, 3);
// 010
