Fixed is a TypeScript library for working with fixed-point numbers. It provides functionality for performing arithmetic operations and comparisons on fixed-point numbers with customizable precision.

To use Fixed64 in your TypeScript project, you can install it via npm:

npm install as-fixed

Here's how you can use Fixed in your AssemblyScript code:

import{Fixed64}from"as-fixed";// Create fixed-point numbersconstnum1=newFixed64(12345,100);// 123.45constnum2=Fixed64.from("67.89");// 67.89// Perform arithmetic operationsconstsum=Fixed64.add(num1,num2);// 191.34constdifference=Fixed64.sub(num1,num2);// 55.56constproduct=Fixed64.mult(num1,num2);// 838201.05constquotient=Fixed64.div(num1,num2);// 1.819925677constlog=Fixed64.log(10);// 2.302585092994046// You can use operatorsconstpow=num1**5;if(num1>num2){// Do something}elseif(num1===num2){// Do something else}

Constructor

new Fixed64(num: u64, mag: u64 = 0)

Fixed64.from<T>(x: T): Fixed64
