Description
Represents a double-precision floating-point value.
By default in the current implementation, the Real type is equivalent to Double and the size of Real is 8 bytes.
In old Pascal versions the size of Real was 6 bytes. You can use the {$REALCOMPATIBILITY ON} compiler directive to turn Real back into the 6-byte Real48 type.
