[[INTEGER]] is a 2-byte number type definition that can hold whole numerical values.


{{PageSyntax}}
: [[DIM]] ''variable'' AS [[INTEGER]]


* 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 use the [[LONG]] integer type.
* '''QB64''' [[INTEGER]] values greater than 32767 become negative signed values instead of throwing an "overflow" error, as the top bit designates a negative value. See example 1 below.
* '''QB64''' [[_UNSIGNED]] integers can range from  0 to 65535.
* '''QB64''' _UNSIGNED [[_INTEGER64]] values range from 0 to 18446744073709551615
* Many graphic programs require [[INTEGER]] arrays.
* Variable type suffix is % or ~% for [[_UNSIGNED]]. Suffix can also be placed after a literal or hexadecimal numerical value.
* [[LONG]] integers use the '''&amp;''' suffix and [[_INTEGER64]] use the '''&amp;&amp;''' suffix.
* Values can be converted to 2 byte [[ASCII]] string values using [[MKI$]] and back with [[CVI]].
* '''When a variable has not been defined 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.'''


{{PageExamples}}
''Example 1:'' QBasic signed integers were limited from -32768 to 32767, but could not exceed 32767 or it would error:
{{CodeStart}} '' ''
{{Cl|DO...LOOP|DO}}: {{Cl|_LIMIT}} 2000
  i% = i% + 1
  {{Cl|PRINT}} i%
{{Cl|LOOP}} {{Cl|UNTIL}} i% = 0 '' ''
{{CodeEnd}}
:''Explanation:'' In '''QB64''' the count will go to 32767, then count up from -32768 to 0 before repeating the process without error. 


''Example 2:'' When a signed '''QB64''' INTEGER value exceeds 32767, the value may become a negative value:
{{CodeStart}} '' ''
i% = 38000
{{Cl|PRINT}} i% '' ''
{{CodeEnd}}{{OutputStart}}-27536
{{OutputEnd}}
:''Explanation:'' Use an [[_UNSIGNED]] INTEGER or a ~% variable type suffix for only positive integer values up to 65535.


''Example 3:'' In '''QB64''' [[_UNSIGNED]] INTEGER values greater than 65535 cycle over again from zero:
{{CodeStart}} '' ''
i~% = 70000
{{Cl|PRINT}} i~% '' ''
{{CodeEnd}}{{OutputStart}} 4464
{{OutputEnd}}
:''Explanation:'' In QB64 an unsigned integer value of 65536 would be 0 with values increasing by the value minus 65536.
