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


Syntax:

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 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!
