Name
$RealCompatibility Compiler Directive
Syntax
{$RealCompatibility Off} // default
{$RealCompatibility On}Scope
Local
Description
When you enable the
$RealCompatibility
directive, the compiler
makes the Real type equivalent to
Real48. By default, Real is
equivalent to Double. This directive exists for
backward compatibility. New programs should use the new
floating-point types (Single,
Double, and Extended). If you
must read an old Real value from a file, you can
use Real48.
