* [[LONG]] integer values range from -2147483648 to 2147483647.
|
|
* '''QB64''''s [[_UNSIGNED]] [[LONG]] integer values range from 0 to 4294967295.
|
|
* '''QB64''' [[_UNSIGNED]] [[_INTEGER64]] values range from 0 to 18446744073709551615.
|
|
* Decimal point values assigned to a [[LONG]] variable will be rounded to the nearest whole number.
|
|
* The LONG variable type suffix is & or ~& for [[_UNSIGNED]]. Suffix can also be placed after a literal or hexadecimal numerical value.
|
|
* [[_INTEGER64]] uses the '''&&''' or '''~&&''' [[_UNSIGNED]] suffix.
|
|
* Values can be converted to 4 byte [[ASCII]] string values using [[MKL$]] and back with [[CVL]].
|
|
* '''When a variable has not been assigned or has no type suffix, the type defaults to [[SINGLE]].'''
|
|
* '''Warning: QBasic keyword names cannot be used as numerical variable names with or without the type suffix.'''
