Function: toFixedBigInt()
toFixedBigInt(
value):bigint
Converts a plain JS number price into the fixed-point bigint representation.
Goes through the number's shortest decimal representation (not value * 1e18,
which is inexact above 2^53 — 50000 * 1e18 is not representable as a double), so
every short decimal such as a grid boundary converts exactly. Rounds half up when
the value has more than 18 decimals.
