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...
RuntimeWarning: overflow encountered in short_scalars RuntimeWarning: overflow encountered in short_scalars 在做一个较大数据量的加法时碰到这个问题,按理说python可以自动改变数据类型,把int型变成long甚至longlong,但这里没有。。。 一个可控的方法是用numpy提供的数据类型。(numpy是专门用于科学计算的库,里面...
Given a double type of variable, we have to convert it into an integer in C#. Syntax int_variable = (int)double_variable; Example Input: double a = 123456.789; int b = 0; //type conversion b = (int)a; Output: a: 123456.789 b: 123456 ...
