The storage representation format of long floating-point variables must be d_float. (For information, see Ada Variables and Data Types. This is because the EQUEL runtime system uses that format for floating-point conversions. If your EQUEL program has long_float variables that interact with the EQUEL runtime system, you must make sure they are stored in the d_float format. The default Ada format is g_float. A convenient way to control the format of all long float variables is to issue the acs set pragma program command. For example, by issuing the following command you redefine the program library characteristics for long_float from the default to d_float:

A second remedy to this particular problem is to issue the statement:

in the source file of each compilation unit that uses floating-point variables. You may also explicitly declare the EQUEL variables with type d_float, as defined in package SYSTEM.

The following example is a typical command file that sets up a new Ada program library with the EQUEL package specifications and the d_float numerical format. The name of the new program library is passed in as a parameter:
