/**
 * .what = changes the precision of a price to a target exponent
 * .why = enables precision increase (lossless) and decrease (with round)
 *
 * @example
 * // increase precision (lossless)
 * setPricePrecision({ of: 'USD 50.37', to: 'micro.x10^-6' })
 * // => 'USD 50.370000'
 *
 * @example
 * // decrease precision (requires round)
 * setPricePrecision({ of: 'USD 5.555', to: 'centi.x10^-2' })
 * // => 'USD 5.56' (default half-up)
 *
 * @example
 * // decrease precision with explicit round mode
 * setPricePrecision({ of: 'USD 5.555', to: 'centi.x10^-2' }, { round: 'floor' })
 * // => 'USD 5.55'
