You can pass in - - - a string, which it will parse as an bigInt and throw an `"Invalid integer"` error if the parsing fails. - - a Javascript number, which it will parse as an bigInt and throw an `"Invalid integer"` error if the parsing fails. - - another bigInt. - - nothing, and it will return `bigInt.zero`. - - If you provide a second parameter, then it will parse `number` as a number in base `base`. Note that `base` can be any bigInt (even negative or zero). The letters "a-z" and "A-Z" will be interpreted as the numbers 10 to 35. Higher digits can be specified in angle brackets (`<` and `>`). - -Examples: - - var zero = bigInt(); - var ninetyThree = bigInt(93); - var largeNumber = bigInt("75643564363473453456342378564387956906736546456235345"); - var googol = bigInt("1e100"); - var bigNumber = bigInt(largeNumber); - - var maximumByte = bigInt("FF", 16); - var fiftyFiveGoogol = bigInt("<55>0", googol); - -Note that Javascript numbers larger than `9007199254740992` and smaller than `-9007199254740992` are not precisely represented numbers and will not produce exact results. If you are dealing with numbers outside that range, it is better to pass in strings. - -### Method Chaining - -Note that bigInt operations return bigInts, which allows you to chain methods, for example: - - var salary = bigInt(dollarsPerHour).times(hoursWorked).plus(randomBonuses) - -### Constants - -There are three named constants already stored that you do not have to construct with the `bigInt` function yourself: - - - `bigInt.one`, equivalent to `bigInt(1)` - - `bigInt.zero`, equivalent to `bigInt(0)` - - `bigInt.minusOne`, equivalent to `bigInt(-1)` - -The numbers from -999 to 999 are also already prestored and can be accessed using `bigInt[index]`, for example: - - - `bigInt[-999]`, equivalent to `bigInt(-999)` - - `bigInt[256]`, equivalent to `bigInt(256)` - -### Methods - -#### `abs()` - -Returns the absolute value of a bigInt. - - - `bigInt(-45).abs()` => `45` - - `bigInt(45).abs()` => `45` - -#### `add(number)` - -Performs addition. - - - `bigInt(5).add(7)` => `12` - -[View benchmarks for this method](http://peterolson.github.io/BigInteger.js/benchmark/#Addition) - -#### `and(number)` - -Performs the bitwise AND operation.
