import calculate from 'https://raw.githubusercontent.com/guanghechen/algorithm.ts/main/packages/calculate/src/index.ts'

Usage

// Perform integer arithmetics.
import calculate from 'algorithm.ts/calculate'
// or 
import { calculate } from 'algorithm.ts/calculate'

// Perform decimal arithmetics.
import { decimalCalculate } from 'algorithm.ts/calculate'

// Perform bigint arithmetics.
import { bigintCalculate } from 'algorithm.ts/calculate'

Examples

integer arithmetics

import calculate from '@algorithm.ts/calculate'

calculate('3/2')                  // => 1
calculate('-2+1')                 // => -1
calculate('-2*3 + 2*5*3/6')       // => -1
calculate('(1+(4+5+2)-3)+(6+8)')  // => 23

decimal arithmetics

import { decimalCalculate as calculate } from '@algorithm.ts/calculate'

calculate('3/2')                  // => 1.5
calculate('-2+1')                 // => -1
calculate('-2*3 + 2*5*3/6')       // => -1
calculate('(1+(4+5+2)-3)+(6+8)')  // => 23

bigint arithmetics

import { bigintCalculate as calculate } from '@algorithm.ts/calculate'

calculate('22222222222222222222222222222 * 3333333333333333333323232')
// => 74074074074074074073849599999259259259259259259261504n

Illegal inputs

import calculate from '@algorithm.ts/calculate'
