Unleash all the numbers!!

num is an arbitrary size fixed precision library written in pure javascript. Why? Because once you write one library you want to write all the libraries.

Looking for just integers? Check out int

quick and dirty

npm install num
var num = require('num');

var foo = num('0.1').add('0.2');

// did it work?
console.log(foo.toString());
//'0.3' hell yea

api

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

num (value)

construct a new decimal

valid values are integers, numbers, or strings

add (value)

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

sub (value)

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

mul (value)

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

div (value)

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

neg

return a new num that is the negative

abs

return new num that is the absolute value

abs

return a new num that is the absolute value

cmp (value)

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

lte (value)

return true if self <= value

gt (value)
