AssemblyScript library for arbitrary-precision decimal arithmetic

as-big's Issues

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!

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

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?

`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:

ERROR TS2454: Variable 'cmp' is used before being assigned.
     :
 676 │ qc[qi++] = cmp ? n : ++n;
     │            ~~~

FAILURE 2 compile error(s)

It builds correctly with assembly script 0.24.0.

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.
