类 CalculationUtil

java.lang.Object
cn.vorbote.core.utils.CalculationUtil
public class CalculationUtil extends Object

Calculation Util can help you with high precision math calculation.

This util is made by Github User @sunzsh, and the source code location is Github Gist

Note: Some changes was made by Github user @vorbote because of the deprecation of method BigDecimal.setScale(int, int), all call to this method was moved to BigDecimal.setScale(int, RoundingMode).
