这个计算器是计算C(n,r)值的。 它能够快速计算出很大很大的n和很大的r的值。 比如 C(1000000,100)的值多少？ 下面看看结果： The Value R =: 100 The Value N =: 100,000,0 The Value C(n,r) = 106,621,924,285,106,201,287,451,825,038,562,207,162,667,291,115,250,807,231,138,436,050,033,662,565, 128,461,577,0
oracl 和db2 常用语法比较： 1、取前N条记录 Oracle：Select * from TableName where rownum <= N; DB2：Select * from TableName fetch first N rows only; 2、取得系统日期 Oracle：Select sysdate from dual; DB2：Select current timestamp from sysibm.sysdummy1; 3、空值转换 Oracle：Select
