QML BigInteger Library

It is a library to provide BigInteger for QML. It is derived from the work by Matt McCutchen, and changed the licesne to APACHE-2.0.

The original source is almost unmodified except for C++11 support.

In case you only need to use BigInteger in Qt/C++ application, you may just include all the *.cc files from this project.

Installation

qpm install com.github.benlau.biginteger

2.0 API

import BigInteger 2.0

Usage

BigInteger.create(number)

Create a BigInteger object. You can pass in :

A string
A Javascript number
Undefined - The result will be "0"

BigInteger.abs(number)

BigInteger.gcd(a,b)

BigInteger.pow(base, exp)

BigInteger.fraction(number)

Methods

toString()

equals(number)

add(number)

var num = BigInteger.create("1000").add(3); // 1003

multiply(number)

divide(number)

minus(number)

isNegative()

compare(number)

greater(number)

greaterOrEquals(nunber)

lesser(number)

lesserOrEquals(number)
