    Description :
    _____________

    The ATG operator (arctangent) calculates the arctangent
    of OBJET1 or OBJET1 / OBJET2 if OBJET2 is given.

    The result is expressed in degrees, with range [-90 ; 90]
    for the single argument arctangent and with range  [-180 ; 180] 
    for the two argument arctangent.

    Note 1 :
    __________

    When the OBJET2 object is omitted, the ATG operator calculates
    the arctangent of the OBJET1 object (ENTIER or FLOTTANT type).

    Note 2 :
    __________

    When the ATG operator calculates the arctangent of a CHPOINT,
    it replaces each value of the CHPOINT with its arctangent. The
    RESU1 object is thus of CHPOINT type and has the same structure
    as OBJET2.

    Note 3 :
    __________

    When the ATG operator calculates the arctangent of a CHPOINT
    type OBJET1 divided by the CHPOINT type OBJET2, each value of
    OBJET1 is divided by the corresponding value of OBJET2 if it
    exists (otherwise, an angle of +- 90 degrees is given), then the 
    arctangent is taken. In this case, the RESU1 object is of CHPOINT
    type and has the same structure as OBJET2.
