41   Rotating points in space can be performed by a vector-matrix
42   multiplication. The matrix3x3 class is designed as a helper to the
43   vector3 class for rotating points in space. The rotation matrix may be
44 < initialised by passing in the array of doubleing point values, by
44 > initialised by passing in the array of floating point values, by
45   passing euler angles, or a rotation vector and angle of rotation about
46   that vector. Once set, the matrix3x3 class can be used to rotate
47   vectors by the overloaded multiplication operator. The following
# Line 102 | Line 102 | void matrix3x3::SetupRotMat(double phi,double theta,do
102    generate the 0-matrix. If the length of the axis is close to
103    zero, but not == 0.0, this method may behave in unexpected
104    ways and return almost random results; details may depend on
105 <  your particular doubleing point implementation. The use of this
105 >  your particular floating point implementation. The use of this
106    method is therefore highly discouraged, unless you are certain
107    that the length is in a reasonable range, away from 0.0
