-// Amount compression:
-// * If the amount is 0, output 0
-// * first, divide the amount (in base units) by the largest power of 10 possible; call the exponent e (e is max 9)
-// * if e<9, the last digit of the resulting number cannot be 0; store it as d, and drop it (divide by 10)
-//   * call the result n
-//   * output 1 + 10*(9*n + d - 1) + e
-// * if e==9, we only know the resulting number is not zero, so output 1 + 10*(n - 1) + 9
-// (this is decodable, as d is in [1-9] and e is in [0-9])
