Requirements

• Any Arduino Device: (recommended model) Adafruit Feather HUZZAH with ESP8266 WiFi
• Arduino IDE: https://www.arduino.cc/en/Main/Software

Usage

Initialize the BigNumber library

  BigNumber.begin();

create your BigNumber

  BigNumber bigNum;
  bigNum = "67411411944031530524562029520200239450929984281572279077458355238873731477537";

  BigNumber bigNum = "67411411944031530524562029520200239450929984281572279077458355238873731477537";

modify your BigNumber

  BigNumber bigNum = "67411411944031530524562029520200239450929984281572279077458355238873731477537";
  BigNumber base = 16;
  BigNumber multiplier = base.pow(8);
  bigNum *= multiplier;

Serial.print your BigNumber

  BigNumber bigNum = "67411411944031530524562029520200239450929984281572279077458355238873731477537";
  Serial.println(bigNum);
