Number Formatting
Format numbers to a fixed number of decimal places.
import { format } from 'd3-format';
const formatter = format('.2f');
const formattedNumber = formatter(123.456); // '123.46'Currency Formatting
Format numbers as currency, including symbol, comma separation, and decimal precision.
import { format } from 'd3-format';
const currencyFormatter = format('$,.2f');
const formattedCurrency = currencyFormatter(1234.56); // '$1,234.56'Percentage Formatting
Format numbers as percentages with rounding and no decimal places.
import { format } from 'd3-format';
const percentFormatter = format('.0%');
const formattedPercent = percentFormatter(0.123); // '12%'SI Prefix Formatting
Format numbers using SI prefixes with a specified precision.
import { format } from 'd3-format';
const siFormatter = format('.3s');
const formattedSI = siFormatter(123456); // '123k'Numeral is a standalone library for formatting and manipulating numbers. It offers a wide range of formatting options and is similar to d3-format in its purpose. However, it does not require D3 and has its own syntax for specifying formats.
Accounting.js is a tiny JavaScript library for number, money and currency formatting, which also offers some basic arithmetic and utility functions. It is similar to d3-format in terms of currency formatting but is more focused on accounting and financial operations.
