I disagree. In the case of paths, the current curve's final point is

exactly the same data as the next curve's initial point. 2geom has this

built-in redundancy in path data because it simplifies things a lot. But

it is important to maintain this data duplication. Therefore, these

points should be exactly (binary) equivalent.

but the main problem with floating point values is that depending on the rounding involved on calculations to get to some value, things may be equivalent but not an exact match for all bits.
