{{PageDescription}}
* Can be used in '''QB64 only''' with 32 or 64 bit computers.
* Signed numerical values can range from -9223372036854775808 to 9223372036854775807.
* '''QB64''' {{KW|_UNSIGNED}} {{KW|_INTEGER64}} values range from 0 to 18446744073709551615 on 64 bit computers.
* Variable type suffix is '''&&''' or '''~&&''' for [[_UNSIGNED]]. Suffix can also be placed after a literal or hexadecimal numerical value. 
* Values can be converted to 8 byte [[ASCII]] character strings using [[_MK$]] and back using [[_CV]] in QB64.
* Equivalent to INT8 or unsigned as UINT8 in C programming.
* '''When a variable has not been assigned or has no type suffix, the value defaults to [[SINGLE]].'''
