|
* Integers do not use decimal point values but will round those off to the nearest even whole number.
|
||
|
* Qbasic Integer values can range from -32768 to 32767 without an "overflow" error.
|
||
|
* For larger Integer values Qbasic can use the [[LONG]] Integer values.
|
||
|
* '''QB64''' [[_UNSIGNED]] Integers can range from 0 to 65535.
|
||
|
* '''QB64''' _UNSIGNED [[_INTEGER64]] values range from 0 to 18446744073709551615
|
||
|
* Many Graphic programs require INTEGER arrays or DEFINT.
|
||
|
* Variable type suffix is % or ~% for [[_UNSIGNED]]. Suffix can also be placed after a literal or hexadecimal numerical value.
|
||
|
* [[LONG]] integers use the '''&''' suffix and [[_INTEGER64]] use the '''&&''' suffix.
|
||
|
* Values can be converted to 2 byte [[ASCII]] string values using [[MKI$]] and back with [[CVI]].
|
||
|
* '''When a variable has not been assigned or has no type suffix, the value defaults to [[SINGLE]].'''
|
||
|
* '''Warning: Qbasic keyword names cannot be used as numerical variable names with or without the type suffix!'''
