DOUBLE
From QB64 Wiki
DOUBLE type floating point numerical values use 8 bytes per value.
- DIM variable AS DOUBLE
Description:
- Literal or variable values can range up to 15 decimal point places.
- Qbasic variable suffix type is #. The IDE may add the suffix after literal values.
- Results of mathematical calculations may be approximate or slow in Quickbasic 4.5.
- Use DOUBLE and _FLOAT variables SPARINGLY! They use a lot of program memory.
- 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 8 byte ASCII string values using _MKD$ and back with _CVD.
- 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!
