pub static RECIPROCAL: [u16; 512]Expand description
The reciprocal ROM, built at compile time.
A static rather than a function, which is what makes it a table in the
binary: the generator runs during const evaluation and nothing computes
a reciprocal at run time. An earlier revision computed each entry on
demand, which made every VRSQ pay for a search — see the note on
INVERSE_SQUARE_ROOT.
