What is the Long Data Type (known also as BIGINT)?

Data System Architecture


long is the computer integer data type (ie storage format) that stores integer with at least 32 bit in size and nowdays on 64bit.

Storage and maximum

  • For a signed 64-bit]] integer, the maximum in decimal is 9223372036854775807

Vs Integer

The integer data type stores also integer but on a smaller length:

  • requiring less storage
  • at the cost of a smaller range of possible number
