cast from float to double about manif HOT 4 CLOSED

Hello,

Thanks for raising this issue, I'll look at it.

Not much more elegant but the following should work,

d = f.coeffs().cast<double>().normalize();

Something else you could do is to use an intermediate quaternion object, something along the lines of,

d.quat( f.quat().cast<double>().normalize() );

Thanks for your reply.
Normlizing on coeffs may work for SO3,SO2, but wont work for SE3, SE2。
Maybe we could do normlization in function "cast" (before normlization check in constructor) depending on whether it is cast from higher precision to lower or vice versa
