PowerAda Other Packages
Additional Ada95 source is provided under $POWERADA/contrib. These are described below. Additional source may be delivered under this directory as it becomes available or users request it. Distributions of other public-domain tools such as xemacs are also located in this directory.
math
This directory provides source for both thin and thick bindings to the AIX libm math library routines. The C interface to these is defined by the file
/usr/include/math.h
. The packages provided are:
Libm_Interface (libm.ada) - a thin binding to the functions in /usr/lib/libm.a
Generic_Math (gmath*.ada) - an interface to Libm_Interface for type Long_Float that supports exception checking of results. An instantiation of this package with checking enabled is provided as package Math in the file math.ada
. An instantiation of this package with checking disabled is provided as the package Fast_Math in the file fastmath.ada
.
Generic_Elementary_Functions (gef_*.ada) - an Ada83 implementation of an earlier version of the predefined Ada95 package Ada.Numerics.Generic_ Elementary_Functions. It may be instantiated for any float type. It is implemented with the bindings to libm.a
through the package Generic_Math, and hence performs an explicit conversion of each floating-point argument to type Long_Float. Preinstantiations of the above packages for types Float and Long_Float as Elementary_Functions and Long_Elementary_Functions, respectively, in the file math.ada.
AdaXlibXt
This is the GPL (sort-of-public-domain) subset of the SERC Ada bindings, ported to PowerAda. They provide very complete bindings to Xlib and Xt, and numerous examples. See the file README in the directory $POWERADA/contrib/AdaXlibXt for more information. Contact OC Systems for information on Ada bindings to Motif.
