Longreal
The longreal type is a predefined, simple type that represents a subset
of the real numbers. This type may have more precision and a larger
range than the type real . The range the subset covers is implementation
dependent in HP Pascal. For more details see the HP Pascal/iX
Programmer's Guide or the HP Pascal/HP-UX Programmer's Guide , depending
on your implementation.
