  //str = "117.7 MB"

It supports the following sizes:

Arguments

pretty(123456, true, true, 2);

/*

First arg is size
Second argument is to remove the space from the output
Third argument is to use a single character for the size.
Forth argument is the number of decimal places to return, default is 1.
Fith argument is to return a converted number without the size string.
*/


let str = pretty(1024 * 1024, true);
  //str = "1MB"

    str = pretty(123456789, {nospace: true}) // pretty(123456789, true, true);
  //str = "117.7M"

    str = pretty(123456789, {one: true}) // pretty(123456789, false, true);
  //str = "117.7 M"

    str = pretty(123456789, {one: true, places: 2}) // pretty(123456789, false, true, 2);
  //str = "117.74 M"

   str = pretty(123456789, {one: true, places: 3}) // pretty(123456789, false, true, 3);
 //str = "117.738 M"

   str = pretty(123456789, {numOnly: true}) // pretty(123456789, false, false, false, true);
 //num = 117.7

pretty(mem.available, true, true, false)

work

 pretty(mem.available, true, true, "0")

Changelog

Is there a changelog available? I am wondering what breaking changes occurred between 0.1.0 and 1.0.0. Thanks!

Bower?

Would you consider adding this module to bower as well as npm? I'm using it both on the server and client side but I'm having to inline it for the client side-- Bower would really help.

Thanks,
Ryan

Feature request: ability to specify number of decimals

I like to be able to specify the number of decimals of the result. Currently the module returns a result with a single decimal. I like to have 2 decimals.

Do the viceversa

Any module that does the viceversa?
Like:

toBytes('1MB') // 1048576

Does not work in IE11

Using IE11 and prettysize (Built through webpack), the website doesn't load at all when including prettysize as a package.

You get the following error in the console app.js (6856,1), and the source leads to:

Removing prettysize works. Is there any polyfil needed?
