Retourne l'arc tangent de deux variables <parameter>x</parameter>
|
|
et <parameter>y</parameter>. La formule est :
|
|
" arc tangent (<parameter>y</parameter> / <parameter>x</parameter>) ", et les signes des
|
|
arguments sont utilisés pour déterminer le quadrant du
|
|
résultat.
|
|
</simpara>
|
|
<simpara>
|
|
Cette fonction retourne un résultat en radians,
|
|
entre -PI et PI (inclus).
