num


num is an arbitrary size fixed precision library written in javascript for node.js and browsers

Looking for just integers? Check out int

``
npm install num
`

`javascript
var num = require('num');

// ordinary js floating point math
console.log(0.1 + 0.2); // 0.30000000000000004 :(

// with num
console.log(num(0.1).add(0.2).toString()); //'0.3'
`

Besides the num function, all of the other methods operate on the objects returned by num

$3

> construct a new decimal

> valid values are integers, numbers, or strings

$3

> add {value} to our number and return a new num

$3

> subtract {value} from our number and return a new num

$3

> multiply our num by {value} and return a new num

$3

> divide our num by {value} and return a new num

`
// note that div uses the precision of the numerator
num('1').div('3.0') -> 0
num('1.0').div('3') -> 0.3

$3

> compare our value to {value}

> return 0 if self and value are equal, -1 if self < value, 1 if self > value

$3

> return true if self < value

$3

> return true if self <= value

$3

> return true if self > value

$3

> return true if self >= value

$3

> return true if self == value

$3

> return true if self != value
