Returns Absolute value of a float. @param fValue The value to abs. @return The abs of the value. @see java.lang.Math#abs(float)

Returns the arc cosine of a value.<br> Special cases: <ul><li>If fValue is smaller than -1, then the result is PI. <li>If the argument is greater than

Returns the arc sine of a value.<br> Special cases: <ul><li>If fValue is smaller than -1, then the result is -HALF_PI. <li>If the argument is greater

Returns the arc tangent of an angle given in radians.<br> @param fValue The angle, in radians. @return fValue's atan @see java.lang.Math#atan(double)

A direct call to Math.atan2. @param fY @param fX @return Math.atan2(fY,fX) @see java.lang.Math#atan2(double, double)
