{{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.
