Information
This function returns y = atan3(u1,u2,y0) such that
tan(y) = u1/u2 and
y is in the range: -pi < y-y0 < pi.
u2 may be zero, provided u1 is not zero. The difference to
Modelica.Math.atan2(..) is the optional third argument y0 that
allows to specify which of the infinite many solutions
shall be returned:
Syntax
