Atan function

[laurent berger]

Hi,

Thanks you for yours answers
I didn't write that's a bug only that I didn't understand results.
For an end user like me I have learn at school that atan is a function (a
function give only one result) and atan(0) is equal to atan(-0). Scilab
results are mathematically stange. 
In libre office results are like in Scilab so compatible with LIA 2.

best regards 
Laurent Berger
