{{PageDescription}}
|
|
* Values can range up to 7 digits. Decimal point accuracy depends on whole value places taken.
|
|
* Single is the '''default variable type''' assigned to undefined variables without a type suffix.
|
|
* Variable suffix type designation is '''!'''. Suffix can also be placed after a literal numerical value by user or automatically by the IDE.
|
|
* Values returned may be expressed using exponential or [[scientific notation]] using '''E''' for SINGLE or '''D''' for DOUBLE precision.
|
|
* Floating decimal point numerical values cannot be [[_UNSIGNED]]!
|
|
* Values can be converted to 4 byte [[ASCII]] string values using [[_MKS$]] and back with [[_CVS]].
|
|
* '''Warning: QBasic keyword names cannot be used as numerical variable names with or without the type suffix!'''
