* Derive precision for multiple progress with total and values.
*
* This helper dervices a precision that is sufficiently large to show minimum value of multiple progress.
*
* Example1
* - total: 1122
* - values: [325, 111, 74, 612]
* - min ratio: 74/1122 = 0.0659...
* - required precision: 100
*
* Example2
* - total: 10541
* - values: [3235, 1111, 74, 6121]
* - min ratio: 74/10541 = 0.0070...
* - required precision: 1000
*
* @param min A minimum value within multiple values
* @param total A total amount of multiple values
* @returns {number} A precison. Could be 1, 10, 100, ... 1e+10.
