Hi Jean-Francois,

  The following web page gives a short block of code that determines
Euler angles (called heading, attitude, and bank on that page)


  That page also wisely suggests that you shouldn't convert to Euler angles
unless you have to -- for example if you are using a program that will only
accept Euler angles.  They have bad characteristics -- different sets of
Euler angles can be used to represent the same rotation.
