Algorithms of Newlib ?

[Jean-Claude Berges]

Hello all ,

 I have some questions about the Newlib Library:

Which is the origin of the functions like sin, cos,
sqrt, ...of the library?
Are the algorithms identical to those of the
FDLIBM'algorithms ( http://www.validlab.com)?

Does there exist a Ada version, even partial, of this
library?

Thanks in advance.
