unsigned long long

[Data Types]

Description

Unsigned long-long variables are extended size variables for number storage, and store 64 bits (8 bytes). Unlike standard long-longs, unsigned long-longs won’t store negative numbers, making their range from 0 to 18,446,744,073,709,551,615 (2^64 – 1).If doing math with integers, at least one of the numbers must be followed by an ULL, forcing it to be an unsigned long-long.

Example Code

unsigned long long speedOfRobot = 186000000ULL;

Syntax

unsigned long long var = val;

var – your unsigned long-long variable name
val – the value you assign to that variable
