Revision as of 14:43, 9 October 2017 by imported>SMcNeill (-)
LONG defines a variable as a 4 byte number type definition for larger INTEGER values.
Syntax
- 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.
