long long

[Data Types]

描述

Long-long variables are extended size variables for number storage, and store 64 bits (8 bytes), from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

If doing math with integers, at least one of the numbers must be followed by an LL, forcing it to be a long long.

範例程式碼

long long speedOfRobot = 186000000LL;

語法

long long var = val;

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