books on numerical programming in Ada

[Ada novice <posts@gmx.us>]

Hi,
    My interest being purely using numerical methods with Ada, I would
like to know what publications are out there apart the Annex G of the
RM? From what I've seen  on the web, we have the books:

1. Scientific Ada, published in 1987
2. Applied Ada, published in 1986

and from an earlier post here on comp-lang.Ada, I saw mention of the
book: Algorithmique numérique et Ada, published in 1994 (This is a
French book). The latter seems to be really unavailable for purchase.
Does any one know where this book can be bought?

Any other books published which focus slightly more on the aspects of
Ada numerical programming?

Thanks
YC
