int LVecBase4i::compare_to ( const LVecBase4i other,
int  threshold 
) const
inline

Sorts vectors lexicographically, componentwise.

Returns a number less than 0 if this vector sorts before the other one, greater than zero if it sorts after, 0 if they are equivalent (within the indicated tolerance).

Writes the vector to the Datagram using add_stdfloat().

This is appropriate when you want to write the vector using the standard width setting, especially when you are writing a bam file.

inline

Writes the vector to the Datagram using add_float32() or add_float64(), depending on the type of floats in the vector, regardless of the setting of Datagram::set_stdfloat_double().
