_FLOAT

_FLOAT numerical values offer the maximum floating-point decimal precision available using QB64.

Syntax

DIM variable AS _FLOAT

Description

• QB64 always allocates 32 bytes to store this value.
• It is safe to assume this value is at least as precise as DOUBLE.
• Under the current implementation it is stored in a 10-byte floating point variable.
• _FLOAT variables can also use the ## variable name type suffix.
• 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 32 byte ASCII strings using _MK$ and back with _CV.
• When a variable has not been assigned or has no type suffix, the value defaults to SINGLE.
