等到出了问题的时候,才发现参数是double的构造方法的详细说明中有这么一段: Note: the results of this constructor can be somewhat unpredictable. One might assume that new BigDecimal(.1) is exactly equal to .1, but it is actually equal to .1000000000000000055511151231257827021181583404541015625. This is s...

在采用C++编写算法时,经常需要判断两个浮点数是否相等。由于计算精度的原因,采用“==”运算符是不可行的。下面给出采用C++11标准判断两个浮点数是否相等的代码: // Test whether two float or double numbers are equal. // ulp: units
public boolean equals(Object ob); Parameters Object ob– represents the Object to compare with. Return Value The return type of this method isboolean, it returns a Boolean value. it returns a Boolean value. If both objects are equal it returns "true", else it returns "false". ...
