Polar(z)

Construct a polar representation of z.

Polar(radius::Real, azimuth::Real)

Construct a polar value with the given radius and angle.

Spherical(z)

Construct a spherical representation of the value z.

Spherical(latitude, azimuth)

Construct a spherical representation with given latitude in [-π/2,π/2] and azimuth.

S2coord(u::Spherical)

Convert the spherical value to a 3-vector of coordinates on the unit sphere.

real_type(z)

Return the base type of a real or complex float z, i.e., the type of its real part.
