Given that it is a signed data type, this gives it the range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. So we already established that BigIntegers are โBigโ.

WebThe long data type is a 64-bit two's complement integer. Its value-range lies between -9,223,372,036,854,775,808 (-2^63) to 9,223,372,036,854,775,807 (2^63 -1) (inclusive). Its minimum value is - 9,223,372,036,854,775,808and maximum value is 9,223,372,036,854,775,807.
