Math

Overview

The framework re-exports lodash-es via the facade for math operations. These provide consistent arithmetic, rounding, and aggregation utilities.

Import

import { lodash } from "@/framework/facade.js";

Common Methods

Method	Purpose
lodash.add(a, b)	Adds two numbers
lodash.subtract(a, b)	Subtracts b from a
lodash.multiply(a, b)	Multiplies two numbers
lodash.divide(a, b)	Divides a by b
lodash.sum(array)	Returns the sum of an array
lodash.sumBy(array, iteratee)	Sums by iteratee
lodash.mean(array)	Returns the mean average
lodash.meanBy(array, iteratee)	Mean by iteratee
lodash.max(array)	Returns the maximum value
lodash.maxBy(array, iteratee)	Max by iteratee
lodash.min(array)	Returns the minimum value
lodash.minBy(array, iteratee)	Min by iteratee
lodash.ceil(number, precision)	Rounds up to precision decimal places
lodash.floor(number, precision)	Rounds down to precision decimal places
lodash.round(number, precision)	Rounds to precision decimal places

Usage

import { lodash } from "@/framework/facade.js";

const prices = [19.99, 29.99, 39.99, 49.99];

lodash.sum(prices);
// 139.96

lodash.mean(prices);
// 34.99

lodash.round(3.14159, 2);
// 3.14

lodash.ceil(3.14159, 2);
// 3.15

const items = [
  { name: "A", price: 10 },
  { name: "B", price: 20 },
  { name: "C", price: 30 },
];

lodash.sumBy(items, "price");
// 60

lodash.maxBy(items, "price");
// { name: "C", price: 30 }
