爱尔兰计算器java实现。实现爱尔兰B公式和爱尔兰C公式的计算，知道三个参数中任意两个可以得到第三个参数的值。同时，利用了BigDecimal和BigInteger类，理论上，只要时间足够，程序可以实现对于任意大小的数的计算。另外，程序可以绘制B-C图和B-a图，还可以显示大群化效应。-Irish calculator java. B formula of Ireland and the Irish C formula calculation, know any two of the three parameters can be the third parameter value. Use BigDecimal and BigInteger class, in theory, as long as enough time, the program can be the calculation of the number of any size. In addition, the program can draw BC map and Ba diagram can also display a large group of effects.
