pub const ONE_BAND_BC_RELATIVE_TOLERANCE_V1: f64 = 1.0e-6;Expand description
How closely a one-band ProjectileV1::bc_segments ladder’s BC must match the scalar
ballistic_coefficient, relative to the larger of the two: one part in a million. That
forgives rounding nobody chose, such as a BC held as an f32 (0.243f32 reads back as
0.24300000071525574) or converted between units and back, but not a different value: 0.172
against 0.1724 is still refused. Within it, the band’s BC is the one that flies.
