Functions

bin_to_cents

Converts a fractional bin to a USD price in cents. For a $D output at price P: sats = D * 1e8 / P, so P = 10^(10 - bin/200) dollars, where 10 = log10($100 reference * 1e8 sats/BTC).

cents_to_bin

Converts a USD price in cents to a fractional bin (inverse of bin_to_cents).

sats_to_bin

Maps a satoshi value to its log-scale bin index. bin = round(log10(sats) * BINS_PER_DECADE).
