More on Ada and numerics

[Reinert Korsnes]

Thanks for the answers on this group with respect to Ada and Linear Algebra.

I am so used to the math intrinsic functions in Fortran.
Is there an Ada package imitating those Fortran intrinsics ?

For example, do I have to make my own Ada version of max(X,Y) ?
Or is it something I have been missing and this is included
in the standard core of Ada ?

(Yes, I am a new practioner of Ada - due to GNAT).

OObs, sorry my ignorance, 
found "functional attributes", max becomes:

 Float'(X,Y);    

I must read my book more carefully :-)

Hmm, Float'Max(X,Y);

Yes, nice to discuss  :-)

Check the following in the Ada Reference Manual (ARM - available
on-line):

A.5 The Numerics Packages
Annex K (informative): Language-Defined Attributes

I think you'll find lots of support there for math. You might want to
look at my website and/or head directly to http://www.adapower.com/ to
find links to Ada resources and various examples of Ada programming that
you may be able to adapt.
