as-big's Issues

Is this supposed to work in Node.js?

...and would there be any benefits to using it that way.

Currently getting Error: Cannot find module 'as-big' error.

Proper attribution

Looks good, Tomas.

This is a polite request for you to include my copyright notice and license with this software, as it is clearly built very substantially on my hard work.

Is it ready to production?

Hi. Great work @ttulka!

Until we have a native decimal type in JS it seems as-big is the best option I found to our financial (in production) applications.

So we'd like to know in what scenarios as-big has been used and if it has been used in production env.

Thanks!

different value in toString on big decimal numbers

I am implementing some math algorithms in assembly script to use as module in node JS.

In some cases, when I try to parse Big to number() o just use the method toF64, it return the fallowing message.

and when I try to make an conversion to String the method return an completely different number, like 39264 , what I had no idea the reason.

I also try do debug line to line in visual studio code do catch the error, but I had no success to configure the debugger for it, can you exemplify how to?

Is it possible to run directly in javascript?

I'm new to webassembly and I have a question about using the lib.

I read your journey of learning webassembly, but I have a question about the possibility of calling the lib after compiled in javascript

inside index.ts:

import { basics0, basics1, basics2, basics3 } from './basics';
import Big from 'as-big/Big';

export { 
    basics0, basics1, basics2, basics3, 
    Big
};

inside index.js

const fs = require("fs");
const loader = require("@assemblyscript/loader");
const wasm = loader.instantiateSync(fs.readFileSync(__dirname + "/build/optimized.wasm"), {});
module.exports = wasm.exports;

const { __getString } = wasm.exports;

console.log('ONE #0:', wasm.exports.Big.ONE);

Every function calling as-big must be inside assembly folder and compiled?

Thanks a lot

`cmp` is used before being assigned assembly script >= 0.25.0

Starting with assembly script 0.25.0, the build fails with the following error:

     :

It builds correctly with assembly script 0.24.0.
