HP Data Entry and Forms Management System (VPLUS/V)

HPPA INTRINSICS 

Introduction 

On the MPE/V and previous systems, Hewlett Packard represented real or
floating point numbers in a format unique to each machine.  However, on
the MPE/XL systems, these numbers are represented in a format that
conforms with an IEEE standard.  This means that programs running in
native mode on MPE/XL systems will deal with numbers stored in the IEEE
format.  VPLUS/V will be running in compatibility mode, however, and will
thus deal with numbers stored in the MPE/V format.

Currently, VPLUS/V offers intrinsics that will accept a real number n the
MPE/V format, convert it to its equivalent external representation and
put it into a form's data buffer.  The four HPPA intrinsics described
below have been developed to allow programs running in native mode to
perform the same operations on a number stored in the IEEE format.


NOTE  Use these intrinsics only if you are programming entirely in native
      mode.  If you are accessing a database in compatibility mode, you
      must use the VPLUS/V intrinsics, VGET/PUTtype.
