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

## Syntax

- 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
**&**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 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.**

## Example(s)

QBasic signed integers were limited from -32768 to 32767, but could not exceed 32767 or it would error:

```
DO: _LIMIT 2000
i% = i% + 1
PRINT i%
LOOP UNTIL i% = 0
```

Explanation:InQB64the count will go to 32767, then count up from -32768 to 0 before repeating the process without error.

When a signed **QB64** INTEGER value exceeds 32767, the value may become a negative value:

```
i% = 38000
PRINT i%
```

```
-27536
```

Explanation:Use an _UNSIGNED INTEGER or a ~% variable type suffix for only positive integer values up to 65535.

In **QB64** _UNSIGNED INTEGER values greater than 65535 cycle over again from zero:

```
i~% = 70000
PRINT i~%
```

```
4464
```

Explanation:In QB64 an unsigned integer value of 65536 would be 0 with values increasing by the value minus 65536.
